Dictionary attributes

Dictionary attributes alter the behavior of the table or element that the dictionary record describes. Administrators can add or modify dictionary attributes.

Adding an Attribute

To add an attribute to a table or field, navigate to the System Dictionary record for the Dictionary entry, and add the attribute to the Attributes field. Attributes are comma-separated; if attributes exist on a dictionary record, add a comma, with no spaces, before adding an attribute.

For an attribute that accepts true/false values:

To specify a value of true, you can either enter attribute or attribute=true.
To specify a value of false, you can either ensure that the attribute does not appear or enter attribute=false. To maintain values during upgrades, do not remove an attribute that is on a table by default.

Maintaining Attribute Values for Upgrades

If you remove an attribute that is part of the base system, it is automatically restored during an upgrade. To prevent upgrades from changing the desired behavior of your system, leave the attribute on the table or field, but set its value as desired.

For example, if a field has the attribute knowledge_search=true by default, do not remove the attribute to set it to false; rather set it to knowledge_search=false.

Available attributes

Table 1. Available dictionary attributes
Name	Value	Target Element	Description
allow_null	true/false	field_name field	If present or true, allows entering `"None"` as the field
allow_public	true/false	table_name field	If true, the table name field will display tables from all scopes instead of only the current scope.
allow_references	true/false	field_name field	If true, a tree is displayed to select from that includes reference fields so you can dot-walk.
approval_user	name of field containing the user(s) for the approval type this field represents	integer field	The fields of the table are used to perform the lookup using a matcher. Approvals are specified as fields in the table that have an attribute of approval_user=<field_name>, where <field_name> indicates the field in the table that contains the users for this approval type. Fields with this attribute contain an integer value that indicates the sequence for the approvals. All approval fields with the same sequence number indicate that multiple approvals are required before continuing. Approvals are requested in the order of the sequence numbers. For example, all approvals with sequence number 100 must be approved before approvals with sequence number 200 are requested.
attachment_index	true/false	any table	If true, attachments on the table are indexed for search purposes. See Index attachments on a table.
barcode	true/false	string field	Allows a string field in the Using the ServiceNow Classic mobile app to access a camera on a mobile device to scan and process a bar code.
base_table	name of base table type	table_name field	A table_name field allows the user to choose any table derived from the table specified by this attribute. By default, the base table itself is also included in the choice list (but see skip_root to turn off this behavior).
calendar_elements	list of field names, separated by semicolons (";")	any calendar event table	Specifies a list of fields to be used when constructing the description of a calendar event. If not specified, the usual display name plus short description are used. The calendar_elements attribute does not support derived (dot-walked) fields.
collection_interval	interval specified as "HH:MM:SS" (like "01:02:30" for one hour, two minutes, and thirty seconds)	collection field	Specifies the interval of metrics collection.
close_states	inactive state integer values	task state field	Used by the TaskStateUtil API — identifies the list inactive state values delimited by semicolons (;)

detail_row	name of field to display in detail row	any table	Displays the value of the specified field as a detail row for each record in the list view. UI15 is required to use this attribute. Note: If different detail_row attributes are defined for a parent table and a child table, the system uses the child table attribute.
document_viewer_audit	view, download, or all	any table	When the Document Viewer is enabled, this attribute keeps a record of user actions performed on attachments. The values are: view: enables an audit when users view an attachment download: supplies audit information for only downloaded attachments all: shows audit information when attachments are viewed and downloaded
email_client	true/false	any table	If present or true, causes an icon (an envelope) to appear in the more options menu in the form header. If clicked, a popup email client appears.
exclude_auto_recovery	true/false	any table	Disables automatic recovery of draft records for this table and its extensions.
extensions_only	true/false	any table	Table should only have records in tables that extend it. For example, the Task table has this attribute because you would create incident, problem, change records, and not task records.
field_list_selector	true/false	any glide_list	Allows the user to select a field from the dependent table (or current if dependent is not specified). This attribute is used in some workflow activities.
field_decorations	UI Macro name list, separated by semicolons (";")	most fields (except list and multiline text fields)	Similar to ref_contributions, causes the named UI macro to be invoked when the field is rendered on a form.
format	format name	any numeric field	Specifies a named format to use instead of the standard numeric formatting. Options are: glide_duration: Formats a time specified in milliseconds as ddd hh:mm:ss. none: Disables automatic number formatting (for example, changes 2,500 to 2500).
glide.db.oracle.ps.query	true/false	any table	If present and false, prevents the use of Oracle prepared queries on the table.
global_visibility	true/false	any table with a sys_domain column	If present or true, makes this table visible globally even if there are domain restrictions (that is, the sys_domain field has a value).
hasLabels	true/false	any table	If present or true, marks this table as being the target of a label at some point. This attribute can be set manually, but it is set automatically whenever a label is generated. When true, the label engine runs on any change to the table, updating the labels as needed.
hasListeners	true/false	any table	If present or true, marks this table as available for listeners to get events (insert, update, delete) on.
hasWorkflow	true/false	any table	Tells the workflow engine to listen for changes to the table, firing events to a workflow when a record associated with a particular workflow has changed.
html_sanitize	true/false	any HTML or translated HTML field	If present or true, HTML sanitization is enabled for the selected HTML or Translated HTML field. By default, HTML Sanitization is performed on all HTML and Translated HTML fields. Set this attribute to false to disable sanitization.
html_sanitize_config	name of custom sanitizer configuration file	any HTML or translated HTML field	If present, sanitization is performed using the specified configuration file instead of the default platform sanitizer. For example, the Embedded Help [sys_embedded_help_content] table uses a specified file (EmbeddedHelpSanitizerConfig) for the help Content field.
icons	name of JavaScript class	any workflow field	Specifies a JavaScript class that produces workflow icons.
image	relative path of image file	any table	Specifies an image file to be used when the table is used in a module or BSM map. This specification overrides the icons that would otherwise be used for the table.
include_container_types	true/false	any internal_type field	Causes the field to render with container (split) types as well other types.
isOrder	true/false	any field	Sets the field as the default field used for the sort order in lists. Overriden by the ORDERBY URL parameter or user's sort preferences.
iterativeDelete	true/false	any table	If present or true, forces all row deletes to be executed iteratively. Otherwise, some deletes may be performed using a more efficient bulk method.
json_view	true/false	any table	Enables an icon next to a field that, when clicked, displays data interchange information if a JSON object is associated with the field.
knowledge_custom	name of JavaScript function	any field	Specifies a JavaScript function to implement a custom knowledge search (see knowledge_search).
knowledge_search	true/false	string fields	If present or true, causes a knowledge search icon (a small book) to appear next to the field. Clicking this icon launches a pop-up window for searching the knowledge base, unless a custom knowledge search function has been specified (see knowledge_custom).
largeTable	true/false	any table	If present or true, marks this table as "large" to preventing table locking with specific MySQL database operations (adding/removing a column/index, compacting a table). Without this attribute (or the smallTable attribute), the glide.db.large.threshold property, or the default value of 5,000, determines whether a table is large.
listen	true/false	any field	If present or true, causes a call to a JavaScript function named <tableName>_<fieldName>Listen, or globalListen if that function does not exist. The function is called with arguments (tableName, fieldName, oldValue, newValue).
live_feed	true/false	any field	If present or true, creates a toggle option on the activity formatter header for incidents, tasks, and problems. The toggle provides the choice between the Live Feed for that record (also known as a document feed) or the activity formatter fields already in use. See Activity formatter for more details.
long_label	true/false	any reference field	Long or short labels refer to the label displayed for reference fields on a form. For example, if the reference field contains the caller’s email address, the long label would be Caller Email, while the short label would just be Email. Usually the placement of the reference field on the form makes it clear what the field represents. The global property (glide.short.labels) is used to specify the type of labels displayed for all reference fields on any form. This global property can be overridden for any reference field by setting the short_label=true or long_label=true attribute for the reference field in the Dictionary.
maintain_order	true/false	any glide_list	If present or true, displays the up/down arrow order buttons to the right of the list of selected items.
mode_toggler	true/false	any composite_name field	If present or true, causes a name mode toggle icon (a small right-pointing triangle) to appear to the right of the label. Clicking this icon causes the field's rendering to change from a text field accepting <tablename>.<fieldname> to a pair of reference choice boxes (one for the table, the other for the field). The latter is the default.
model_class	binary Java class name	any field of type glide_var	Specifies a model variable within Java code. The model must have a class that implements the IVariablesModel interface.
model_field	see description	any field of type glide_var	Identifies a reference field in the record that has the model defined for it. For example, a workflow activity is associated with an activity definition. The activity definition has a related list of questions that make up the model for that activity definition. By using the activity_definition as the model_field for the activity, the model for the workflow activity is built by reading the questions that are defined for the referenced activity definition.
nibble_size	positive integer	any table affected by the table cleaner.	Specifies the maximum number of records the table cleaner can delete in a single operation. The default value for this attribute is 250.
nibble_sleep	true/false	any table affected by the table cleaner.	If false, causes the table cleaner to perform cleanup operations without a pause between each operation.
no_attachment	true/false	any table	If present or true, prevents the attachment icon (a paperclip) from appearing on the form header.
no_attachments	true/false	any table	If present or true, attachments are not checked for and deleted when a record from this table is deleted. Meant for high-activity tables that never have attachments.
no_audit	true/false	any table	If present or true, this field is not audited, even if the table is being audited.
no_audit_delete	true/false	any table	If present or true, a sys_audit_delete record is never created when a record from this table is deleted. Meant for high-activity tables that never need sys_audit_delete information.
no_auto_map	true/false	any table	If true, this field is not mapped during an import set. This attribute is primarily used for LDAP imports.
no_email	true/false	any glide_list field referencing sys_user	If present or true, the email box is removed from the glide_list field like the Watch list field.
no_multiple	true/false	any glide_list field	Hides the select multiple icon.
no_optimize	true/false	any table affected by the table cleaner.	If present or true, prevents the MySQL table compaction operation from running on the specified table. The table compaction operation normally runs after the table cleaner deletes at least 50% of the data in the specified table.
no_separation	true/false	any table	If present or true, marks this table as not participating in domain separation.
no_text_index	true/false	any field on a text indexed table	If a table is text indexed, the no_text_index attribute on a field prevents this field from being included in the text index.
no_truncate	true/false	any string field	In a list view, shows the entire text value of the multitext value in a list, without truncating it. Without this attribute, the string is truncated based on the UI property Number of characters displayed in list cells which is 40 by default.
no_update	true/false	table	Is true for tables in which records are inserted or deleted but not updated. Prevents the system from creating sys_mod_count, sys_updated_by, sys_updated_on fields in the table when it is created. Does not stop the table from being updated. This attribute is used to save space on high volume system tables, such as syslog and sys_audit.
no_view	true/false	any glide_list field	Hides the view selected item icon.
onlineAlter	true/false	any table	Tables with the onlineAlter attribute perform MySQL database operations using online schema changes. Online schema changes provides a lock-free table upgrade when adding, modifying, or removing columns and when adding or dropping indexes. Without online schema changes, these changes to the database lock write access during execution. Online schema changes use additional system resources. Oracle databases do not lock tables by default and do not use online schema changes.
order	numeric value	model variable fields	Used internally only (for model variables).
popup_processor	binary Java class name	any field or table	Specifies a custom popup processor for processing the field (or all fields in a table).
readable	true/false	any conditions field	When true, causes the conditions field to be rendered in any list view as a human-readable condition (instead of the encoded query stored in the database).
ref_ac_columns	list of field names separated by semi-colons	any reference field with an auto completer (see ref_auto_completer)	Specifies the columns whose display values should appear in an auto completion list in addition to the name. See the cmdb_ci field (Configuration Item) on the Incident form for a working example.
ref_ac_columns_search	true/false	any reference field with an auto completer (see ref_auto_completer)	Causes auto-complete to work with all fields specified in the ref_ac_columns attribute. This attribute overrides the default behavior, which searches only the display value column. See Configure auto-complete to match text from any reference field.
ref_ac_display_value	true/false	any reference field with an auto completer (see ref_auto_completer)	Causes the reference field to hide the display value column so that auto-complete only matches text from the columns listed in the ref_ac_columns attribute. This feature requires the use of the AJAXTableCompleter class and the ref_ac_columns, ref_ac_columns_search, and ref_ac_display_value attributes. See Remove the display value column.
ref_ac_order_by	field name	any reference field with an auto completer (see ref_auto_completer)	Specifies the column that is used to order the auto completion list.
ref_auto_completer	JavaScript class name	any reference field (can be applied to a table to affect all reference fields on the table.)	Specifies the name of a JavaScript class (client side) that creates the list auto completion choices. Valid class values include: AJAXReferenceCompleter: Displays matching auto-complete choices as a choice-list. The list only displays the display value column of the reference table. If there is no other auto-completion class specified, reference fields automatically use this class. AJAXTableCompleter: Displays matching auto-complete choices as rows in a table. The table displays the display value column of the reference table and any columns listed in the ref_ac_columns attribute. AJAXReferenceChoice: Displays matching auto-complete choices as a choice-list. The list only displays the display value column of the reference table. Furthermore, the list only displays up to 25 matching choices. If there are more than 25 auto-complete choices, the reference field instead displays the choices with the AJAXTableCompleter class. For more information, see Auto-complete for reference fields.
ref_contributions	UI Macro name list, separated by semicolons (";")	any reference field	Causes the named UI macro to be invoked when the field is rendered on a form.
ref_decoration_disabled	true/false	any reference field	When set to `true`, disables display of the reference icon on a selected field.
ref_list_label	label text	any table	Specifies the title to use in a list banner.
ref_qual_elements	field name list, separated by semicolons (";")	any reference field with a reference_qual field	Specifies a list of fields to be sent back to the server to get an updated reference.
ref_sequence	list of fields in referenced table, separated by top hats ("^")	any reference field	Specifies the fields in the referenced table that should be used to order the choice list. This attribute works like an ORDER BY clause in SQL, with each element in ascending order.
reference_types	list of valid reference types that are clickable separated by semicolons (";")	field_name field	Limits the reference fields that are displayed in the tree to the specified types.
remoteDependent	name of database and table (like "model.matcher")	any script field	Defines the remote (such as, in another database) table that the script depends on.
repeat_type_field	field name	a repeat count field for schedule rotation	Specifies the field that contains the repeat type (daily, weekly, monthly, or yearly).
restrictTo	field name (including indirect, dot-walked field references)	any conditions field	Specifies the field that contains the comma-separated list of fields that the conditions should be restricted to using.
ro_collapsible	true/false	any multiline field	If present or true, causes an icon (either a "+" or a "-") to appear next to the label of the field, allowing the field itself to be expanded or collapsed.
scale	integer	decimal field	Sets the number of decimal places to use on the Decimal field type. The default is 2. This attribute is applied to the Max Length of the field. Note: Increase the Max Length to a value greater than 15 to increase this attribute.
script	a function that returns the contents of the field	any slushbucket field	Allows you to write a script to define what is loaded into the slushbucket field.
short_label	true/false	any reference field	Long or short labels refer to the label displayed for reference fields on a form. For example, if the field contains the caller’s email address, the long label would be Caller Email, while the short label would just be Email. Usually the placement of the field on the form makes it clear what the field represents. The global property (glide.short.labels) is used to specify the type of labels displayed for all reference fields on any form. This global property can be overridden for any reference field by setting the short_label=true or long_label=true attribute for the reference field in the Dictionary.
show_all_tables	true/false	document ID fields	Allows users to select documents from system tables. For example, sys_script or sys_user. By default, users cannot select records from system tables.
show_condition_count	true/false	condition fields	Enables or disables the condition count widget to preview how many records would be returned by a set of conditions. See Add the condition count to a condition field.
skip_root	true/false	table_name field	If present or true, removes the base table from the choice list (see base_table for more details).
sla_basis	list of table names separated by semicolons (";")	any field of date type (glide_date_time, glide_date, due_date, date, or datetime)	Defines the tables for which this field determines the start (open) time of an SLA.
sla_closure	list of table names separated by semicolons (";")	any field of date type (glide_date_time, glide_date, due_date, date, or datetime)	Defines the tables for which this field determines the start (open) time of an SLA.
slushbucket_ref_no_expand	true/false	any reference field	If present or true, prevents users from expanding the field from a form or list slushbucket.
smallTable	true/false	any table	If present or true, marks this table as "small" (that is, not large) for the purposes of our querying strategy. Without this attribute (or the largeTable attribute), the glide.db.large.threshold property, or the default value of 5,000, determines whether the table is large.
start_locked	true/false	any glide_list field	Determines whether the field is locked or unlocked by default. Set the value to false to unlock the field by default.
staticDependent	name of table	any script field	Defines the table that the script depends on.
strip_html_in_pdf	true/false	any field	Attempts to remove HTML tags from a field when that field is exported to a PDF. Most likely useful on HTML fields.

target_form	name of form	any table	Specifies the alternative form to be used when this table is referenced through a popup on a reference field.
text_index_filter_junk	true/false	any table	Set the value to false to disable the junk filter for the table. By default, Zing does not index or search for 2-digit numbers and single character words (unless they are Chinese or Japanese characters). Regenerate the index after disabling the junk filter. This attribute results in a larger table index. For optimal performance, do not apply it unless it is required.
text_search_only	true/false	table_name field	Limits the tables listed to those tables that are searchable by text.
text_index_translations	true/false	any table	If present or true, forces indexes to be recalculated when translated strings are added. Requires sys-admin role to modify. Automatically set for indexed fields that are translated, and to fields that have a translation and are being indexed. The glide.i18n.force_index system property, which defaults to true, overrides this attribute.
time_zone_field	name of field containing the time zone	any schedule date/time field	Specifies the field in the parent record that contains the reference time zone for this field.
timeDimension	true/false	any field of date type (glide_date_time, glide_date, due_date, date, or datetime) in a table subclassed from the task table	If present or true, enables production of time dimension data for use by OLAP (to produce reports based on quarters, weeks, or other time periods). Note: OLAP functionality has been deprecated.
tree_picker	true/false	reference field with reference to a hierarchical table	Displays the hierarchy of reference values in a tree display (such as locations).
ts_weight	integer value	any field	Controls the relative importance of a match in the field for text search. See Control Match Relevance By Field.

Dictionary attributes

Dictionary attributes alter the behavior of the table or element that the dictionary record describes. Administrators can add or modify dictionary attributes.

Adding an Attribute

For an attribute that accepts true/false values:

To specify a value of true, you can either enter attribute or attribute=true.
To specify a value of false, you can either ensure that the attribute does not appear or enter attribute=false. To maintain values during upgrades, do not remove an attribute that is on a table by default.

Maintaining Attribute Values for Upgrades

For example, if a field has the attribute knowledge_search=true by default, do not remove the attribute to set it to false; rather set it to knowledge_search=false.

knowledge_custom	name of JavaScript function	any field	Specifies a JavaScript function to implement a custom knowledge search (see knowledge_search).
knowledge_search	true/false	string fields	If present or true, causes a knowledge search icon (a small book) to appear next to the field. Clicking this icon launches a pop-up window for searching the knowledge base, unless a custom knowledge search function has been specified (see knowledge_custom).
largeTable	true/false	any table	If present or true, marks this table as "large" to preventing table locking with specific MySQL database operations (adding/removing a column/index, compacting a table). Without this attribute (or the smallTable attribute), the glide.db.large.threshold property, or the default value of 5,000, determines whether a table is large.
listen	true/false	any field	If present or true, causes a call to a JavaScript function named <tableName>_<fieldName>Listen, or globalListen if that function does not exist. The function is called with arguments (tableName, fieldName, oldValue, newValue).
live_feed	true/false	any field	If present or true, creates a toggle option on the activity formatter header for incidents, tasks, and problems. The toggle provides the choice between the Live Feed for that record (also known as a document feed) or the activity formatter fields already in use. See Activity formatter for more details.
long_label	true/false	any reference field	Long or short labels refer to the label displayed for reference fields on a form. For example, if the reference field contains the caller’s email address, the long label would be Caller Email, while the short label would just be Email. Usually the placement of the reference field on the form makes it clear what the field represents. The global property (glide.short.labels) is used to specify the type of labels displayed for all reference fields on any form. This global property can be overridden for any reference field by setting the short_label=true or long_label=true attribute for the reference field in the Dictionary.
maintain_order	true/false	any glide_list	If present or true, displays the up/down arrow order buttons to the right of the list of selected items.
mode_toggler	true/false	any composite_name field	If present or true, causes a name mode toggle icon (a small right-pointing triangle) to appear to the right of the label. Clicking this icon causes the field's rendering to change from a text field accepting <tablename>.<fieldname> to a pair of reference choice boxes (one for the table, the other for the field). The latter is the default.
model_class	binary Java class name	any field of type glide_var	Specifies a model variable within Java code. The model must have a class that implements the IVariablesModel interface.
model_field	see description	any field of type glide_var	Identifies a reference field in the record that has the model defined for it. For example, a workflow activity is associated with an activity definition. The activity definition has a related list of questions that make up the model for that activity definition. By using the activity_definition as the model_field for the activity, the model for the workflow activity is built by reading the questions that are defined for the referenced activity definition.
nibble_size	positive integer	any table affected by the table cleaner.	Specifies the maximum number of records the table cleaner can delete in a single operation. The default value for this attribute is 250.
nibble_sleep	true/false	any table affected by the table cleaner.	If false, causes the table cleaner to perform cleanup operations without a pause between each operation.
no_attachment	true/false	any table	If present or true, prevents the attachment icon (a paperclip) from appearing on the form header.
no_attachments	true/false	any table	If present or true, attachments are not checked for and deleted when a record from this table is deleted. Meant for high-activity tables that never have attachments.
no_audit	true/false	any table	If present or true, this field is not audited, even if the table is being audited.
no_audit_delete	true/false	any table	If present or true, a sys_audit_delete record is never created when a record from this table is deleted. Meant for high-activity tables that never need sys_audit_delete information.
no_auto_map	true/false	any table	If true, this field is not mapped during an import set. This attribute is primarily used for LDAP imports.
no_email	true/false	any glide_list field referencing sys_user	If present or true, the email box is removed from the glide_list field like the Watch list field.
no_multiple	true/false	any glide_list field	Hides the select multiple icon.
no_optimize	true/false	any table affected by the table cleaner.	If present or true, prevents the MySQL table compaction operation from running on the specified table. The table compaction operation normally runs after the table cleaner deletes at least 50% of the data in the specified table.
no_separation	true/false	any table	If present or true, marks this table as not participating in domain separation.
no_text_index	true/false	any field on a text indexed table	If a table is text indexed, the no_text_index attribute on a field prevents this field from being included in the text index.
no_truncate	true/false	any string field	In a list view, shows the entire text value of the multitext value in a list, without truncating it. Without this attribute, the string is truncated based on the UI property Number of characters displayed in list cells which is 40 by default.
no_update	true/false	table	Is true for tables in which records are inserted or deleted but not updated. Prevents the system from creating sys_mod_count, sys_updated_by, sys_updated_on fields in the table when it is created. Does not stop the table from being updated. This attribute is used to save space on high volume system tables, such as syslog and sys_audit.
no_view	true/false	any glide_list field	Hides the view selected item icon.
onlineAlter	true/false	any table	Tables with the onlineAlter attribute perform MySQL database operations using online schema changes. Online schema changes provides a lock-free table upgrade when adding, modifying, or removing columns and when adding or dropping indexes. Without online schema changes, these changes to the database lock write access during execution. Online schema changes use additional system resources. Oracle databases do not lock tables by default and do not use online schema changes.
order	numeric value	model variable fields	Used internally only (for model variables).
popup_processor	binary Java class name	any field or table	Specifies a custom popup processor for processing the field (or all fields in a table).
readable	true/false	any conditions field	When true, causes the conditions field to be rendered in any list view as a human-readable condition (instead of the encoded query stored in the database).
ref_ac_columns	list of field names separated by semi-colons	any reference field with an auto completer (see ref_auto_completer)	Specifies the columns whose display values should appear in an auto completion list in addition to the name. See the cmdb_ci field (Configuration Item) on the Incident form for a working example.
ref_ac_columns_search	true/false	any reference field with an auto completer (see ref_auto_completer)	Causes auto-complete to work with all fields specified in the ref_ac_columns attribute. This attribute overrides the default behavior, which searches only the display value column. See Configure auto-complete to match text from any reference field.
ref_ac_display_value	true/false	any reference field with an auto completer (see ref_auto_completer)	Causes the reference field to hide the display value column so that auto-complete only matches text from the columns listed in the ref_ac_columns attribute. This feature requires the use of the AJAXTableCompleter class and the ref_ac_columns, ref_ac_columns_search, and ref_ac_display_value attributes. See Remove the display value column.
ref_ac_order_by	field name	any reference field with an auto completer (see ref_auto_completer)	Specifies the column that is used to order the auto completion list.
ref_auto_completer	JavaScript class name	any reference field (can be applied to a table to affect all reference fields on the table.)	Specifies the name of a JavaScript class (client side) that creates the list auto completion choices. Valid class values include: AJAXReferenceCompleter: Displays matching auto-complete choices as a choice-list. The list only displays the display value column of the reference table. If there is no other auto-completion class specified, reference fields automatically use this class. AJAXTableCompleter: Displays matching auto-complete choices as rows in a table. The table displays the display value column of the reference table and any columns listed in the ref_ac_columns attribute. AJAXReferenceChoice: Displays matching auto-complete choices as a choice-list. The list only displays the display value column of the reference table. Furthermore, the list only displays up to 25 matching choices. If there are more than 25 auto-complete choices, the reference field instead displays the choices with the AJAXTableCompleter class. For more information, see Auto-complete for reference fields.
ref_contributions	UI Macro name list, separated by semicolons (";")	any reference field	Causes the named UI macro to be invoked when the field is rendered on a form.
ref_decoration_disabled	true/false	any reference field	When set to `true`, disables display of the reference icon on a selected field.
ref_list_label	label text	any table	Specifies the title to use in a list banner.
ref_qual_elements	field name list, separated by semicolons (";")	any reference field with a reference_qual field	Specifies a list of fields to be sent back to the server to get an updated reference.
ref_sequence	list of fields in referenced table, separated by top hats ("^")	any reference field	Specifies the fields in the referenced table that should be used to order the choice list. This attribute works like an ORDER BY clause in SQL, with each element in ascending order.
reference_types	list of valid reference types that are clickable separated by semicolons (";")	field_name field	Limits the reference fields that are displayed in the tree to the specified types.
remoteDependent	name of database and table (like "model.matcher")	any script field	Defines the remote (such as, in another database) table that the script depends on.
repeat_type_field	field name	a repeat count field for schedule rotation	Specifies the field that contains the repeat type (daily, weekly, monthly, or yearly).
restrictTo	field name (including indirect, dot-walked field references)	any conditions field	Specifies the field that contains the comma-separated list of fields that the conditions should be restricted to using.
ro_collapsible	true/false	any multiline field	If present or true, causes an icon (either a "+" or a "-") to appear next to the label of the field, allowing the field itself to be expanded or collapsed.
scale	integer	decimal field	Sets the number of decimal places to use on the Decimal field type. The default is 2. This attribute is applied to the Max Length of the field. Note: Increase the Max Length to a value greater than 15 to increase this attribute.
script	a function that returns the contents of the field	any slushbucket field	Allows you to write a script to define what is loaded into the slushbucket field.
short_label	true/false	any reference field	Long or short labels refer to the label displayed for reference fields on a form. For example, if the field contains the caller’s email address, the long label would be Caller Email, while the short label would just be Email. Usually the placement of the field on the form makes it clear what the field represents. The global property (glide.short.labels) is used to specify the type of labels displayed for all reference fields on any form. This global property can be overridden for any reference field by setting the short_label=true or long_label=true attribute for the reference field in the Dictionary.
show_all_tables	true/false	document ID fields	Allows users to select documents from system tables. For example, sys_script or sys_user. By default, users cannot select records from system tables.
show_condition_count	true/false	condition fields	Enables or disables the condition count widget to preview how many records would be returned by a set of conditions. See Add the condition count to a condition field.
skip_root	true/false	table_name field	If present or true, removes the base table from the choice list (see base_table for more details).

sla_closure	list of table names separated by semicolons (";")	any field of date type (glide_date_time, glide_date, due_date, date, or datetime)	Defines the tables for which this field determines the start (open) time of an SLA.
slushbucket_ref_no_expand	true/false	any reference field	If present or true, prevents users from expanding the field from a form or list slushbucket.
smallTable	true/false	any table	If present or true, marks this table as "small" (that is, not large) for the purposes of our querying strategy. Without this attribute (or the largeTable attribute), the glide.db.large.threshold property, or the default value of 5,000, determines whether the table is large.
start_locked	true/false	any glide_list field	Determines whether the field is locked or unlocked by default. Set the value to false to unlock the field by default.
staticDependent	name of table	any script field	Defines the table that the script depends on.
strip_html_in_pdf	true/false	any field	Attempts to remove HTML tags from a field when that field is exported to a PDF. Most likely useful on HTML fields.
synch_attachments	true/false	any table	Similar to update_synch but writes the file attachments of the record to update sets. See Index attachments on a table.
table	name of table	field_name field	Displays the fields of the table specified.

target_form	name of form	any table	Specifies the alternative form to be used when this table is referenced through a popup on a reference field.
text_index_filter_junk	true/false	any table	Set the value to false to disable the junk filter for the table. By default, Zing does not index or search for 2-digit numbers and single character words (unless they are Chinese or Japanese characters). Regenerate the index after disabling the junk filter. This attribute results in a larger table index. For optimal performance, do not apply it unless it is required.
text_search_only	true/false	table_name field	Limits the tables listed to those tables that are searchable by text.
text_index_translations	true/false	any table	If present or true, forces indexes to be recalculated when translated strings are added. Requires sys-admin role to modify. Automatically set for indexed fields that are translated, and to fields that have a translation and are being indexed. The glide.i18n.force_index system property, which defaults to true, overrides this attribute.
time_zone_field	name of field containing the time zone	any schedule date/time field	Specifies the field in the parent record that contains the reference time zone for this field.
timeDimension	true/false	any field of date type (glide_date_time, glide_date, due_date, date, or datetime) in a table subclassed from the task table	If present or true, enables production of time dimension data for use by OLAP (to produce reports based on quarters, weeks, or other time periods).
