[UMG] Drag and Drop Inventory?

So, 2 hours later i still have problems. I managed to drag an icon around and reset it by letting loose of my left mouse key.
But i still can’t figure out how to get a widget that lies behind another one. When i’m dragging one item, it is in front of all others.
There is no function to get underlying widgets and “is hovered” isn’t called because the item getting dragged consumes it.

EDIT: Ok, seems like setting the visibility of the dragged item to hit test, lets it pass the hovered event. Let’s see if i get my inventory to work like that.
EDIT2: Nope, doesn’t really help me. Although i can now get the Widget behind this one, i can’t let go of my dragged widget if i’m not on another slot, since nothing
will call the Mouse Button Up event anymore.
