Configuring a user reference on a form
After you add a user reference to a form, you can configure the way that users interact with it. For example, you can display the list of users in your application as a list or as an autocomplete that returns a list of search results.
- In the Explorer panel, click Case types, and then click the case type that you want to open.
 - On the Workflow tab, click Life cycle.
 - Click an assignment or an approval step.
 - Click Configure view.
 - Click the Gear icon in the row of the user-reference field.
 - 
        Select a control type from the list that is displayed.
        
- 
            
Search — Prompts users to search for an existing user by entering a full name or operator ID in an autocomplete field.
 - 
            
Dropdown — Prompts users to select the full name of an existing user from a list.
 
 - 
            
 - Click OK.
 
At run time, users are prompted to select or search for an existing user, based on the control type that you provide. The result, a user ID, is stored in the property that is associated with your user-reference field.
