I don't think it is possible, at least not without some custom code.

I would try to use the REST API from IG for this. Theoretically, it should be possible to display all users as values in a SELECT component via the REST API, although this can certainly lead to performance problems with a larger number of users.

My recommendation would rather be to provide a "search field" and in this search field the users can enter for example a user ID and in the background the REST API is called based on this keyword to search the user catalog. The results are then stored in a SELECT component and when the user selects them then other fields are populated accordingly.

Tobias, 

How can I call the Rest APIs from the Form? Is it on the JS Editor field? 

Do you know where I can find one example of this?

On the right side of the JS Editor in Form Builder, You can expand IG Request / API Examples for two examples.
Select example to insert code at cursor.

Mange, 

At the JS Editor this is what I have. The IG Request / API Examples were supposed to be where is marked? 

I'm using a default form to exemplify. 

Hello,

    Please provide step-by-step instructions for how you go to the page in your screenshot above as your form is missing a lot of data.

Steven,

I did the following steps: 

1. Logged with Diego user, which have the current Authorization Assignements

2. After the login, I selected the House on top right and then select Workflow Dashboard

3. On the Workflow Panel, I clicked on Catalog and then Forms

4. On the Forms page I expanded the Entries to 10 and than selected one default form, the Request Form

5. With the Form open, I clicked on JS Editor

6. The JS Editor opened as before

Hello,

    You can not create or update Identity Governance Request and Approval Forms in Form Builder when you launch it from Workflow Console.  Those are different Forms.  You have to start from Identity Governance.

Also, you can not create custom workflows that are to be utilized for Identity Governance Approval Flows or remediation.  They have to be created from within Identity Governance using 1 of the templates we present.  Once they are created, you can modify them in Workflow Console.
