I have a form where the user can select whether a project is managed by our Project Management org or not. If the drop down field is set to 'Yes', a panel should display below the field and have a few additional fields for the user to fill out. By default this panel is hidden. 

I have it working that the Panel will show, but it isn't very dynamic. The user can select 'Yes', but they have to save/submit the form, close and reopen the form to see the panel. Is there a better way to get this to work? This will definitely hinder performance and cause my users to stay away from this form.
