I am wondering if it is possible to dynamically filter the dropdown list in a control. For example, I have two controls set up. One allows you to filter by User Profile (i.e. IT, nurses, etc.), and the other allows you to filter by User, a specific individual belonging to one of the User Profiles. Right now, if you were to select nurses in the User Profile dropdown, when you open the User dropdown you can still select from all users, not just the nurses. I would like it to be set up so that if someone filters by a certain user profile, when they go the user dropdown, it only shows them users that belong to the selected profile. Is this possible?
