I have been trying to do this since a while, most I have achieved with my simple C2 skills is a buggy transition.
What I want is:
A - B - C - D
four are overlapped with the same instance.
When Instance is dragged from A to B, A becomes empty and Instance in Position B snaps to Position A. Just a simple Drag and drop but without overlap.
If Dragging Instance on A towards D, B goes to A, C goes to B, D goes to C, then drop Instance at D. Sam idea as if you are arranging icons on your desktop.
I couldn't find an example in the forums. Please if you can help let me know.
