I seem to remember being told this wasn't possible in Python, but now I'm wanting to double check this.
When doing User Data, if you put something in a new group, that group can be foldable/collapsable.
Is there any way to do this in a GeDialog in Python?
To see what I mean create a cube, look in the Coords tab. The Freeze Transformation can be collapses. I'm looking to be able to do that in my GeDialog plugin.

Hi Bret,
unfortunately the groupflag which makes the group foldable is broken. It is however possible by using a
button/userarea widget and the GeDialog.HideElement() function.
Here's a quick example:

Is there a way though to make it so it will display the group name still?
