Form groups
Root forms and (optional) dependent forms created as the UI for a custom integration settings tab, a main menu item, or an open pop-up workload action are collectively referred to as a form group.
Example
In this form group, there is the Root form and three dependent forms:
Details
New Form1
New Form2
On Root form, the button, OpenDetails, is configured to open a form when clicked. The dropdown of possible forms to open includes all (and only) the other forms in the extension point UI form group.
