Drop Item Inventory

I have set up the drag and drop for the items.

How can i make it so when an item is dragged outside of the scroll box (Inventory) the item is dropped? I have already got the dropping setup i just need to put it all together.

Have some kind of Master UI Widget that spans across the whole screen. You can implement the drop event there. Also a nice bonus is the ability to compose the whole ui with the UMG designer

I have done some messing around with it and this is what i have got.

At the moment the items can drop on any border including itself how can i stop this so it can only be dropped when dragged on to the left border?
