In Service Portal, you can link JavaScript and CSS files to widgets to create dependencies between widgets and third-party libraries, external style sheets, and angular modules.

1. Create a dependency package.

   A dependency package is a collection of JavaScript and CSS files that can be then connected to a widget.

   1. Navigate to Service Portal > Dependencies.
   2. In the dependency record, define the following fields.

      Field	Description
      Name	The name of your dependency. (Useful for selecting a dependency from a dropdown list.)
      Application	Application scope for the dependency record.
      Include on page load	Select if you want your dependency to be loaded onto the page on the initial page load of Service Portal, or leave unchecked to load the dependency only when the linked widget is loaded onto a page.
      Angular module name	Optional. Define the value if the linked JavaScript is an Angular module. Provide the name of the Angular module being loaded, so that it can be injected into the Service Portal Angular application.

2. Add files to the dependency package.

   After you save the information for your dependency package, use the related lists to add JS and CSS Include files. For each related list, include the following information:

   Field	Description
   Display name	Name of the script include.
   Source	Depending on whether you add a JS Include or a CSS Include, select one of these options from the list: URL UI script (for a JS Include) or Style Sheet (for a CSS Include) For a JS Include, use the UI Script field to reference a UI Script found in System UI > UI Scripts. For the CSS Include, use the Style Sheet field to reference a record in the sp_css table.

3. Add a dependency package to a widget.
   After you have created a dependency package and added files, create a relationship between the dependency and a widget.
   1. Navigate to Service Portal > Widgets and find the widget record you want to add the dependency to.
   2. From the Dependencies related list, click Edit.
   3. In the slushbucket, find the dependency you created and double-click to add it to the selected items column on the right.
   4. Save the page to return to the widget record.
