Related lists appear on forms and show records in tables that have relationships to the current record.

Users can view and modify information in related lists like any other list. Administrators can configure related lists to appear on forms and in hierarchical lists by configuring a form. Related lists do not have a size limit.

Note:

Creating a record using a related list applies the list filter to the record and auto-populates the related field. This behavior applies to reference, string, Boolean, and menu fields when the criteria in the filter is set to is or =.
