Draggable Elements

Hi!
I have a question about draggable elements in case that someone has any experience with that.
I try to drag a group (draggable group) to Drop Area A.
The problem accrue when I drop the group on the drop area. The group hide from the drop area (and move back which is good).
But if I uncheck the option of “Make this group draggable”, it not disappear from the drop area (but then it’s not trigger any workflow)
Someone knows how to fix it?
