Open Popup from Perspective Form widget 8.3

for the form widget is there a way to make it clikable / to open popup

For example what I would like to do is have a dropdown in the form where the options come from the database. Have a button “+” if the desired option isn’t in the dropdown operator can click that and it will open up popup containing the form for that DB table to add that option in.

Some way to do this currently that I am not seeing, or does this a wish list to allow an embeded view or something like that as a widget option?

Not directly

One way I would see would be to check the position of the click event on the form

Another way would be to add a label above as a click trap, depending on the type of input you want
