Hello.
I am trying to use a TreeViewDragDrop plugin for nodes reordering. I have nodes of different types, and nodes of one type could not be dropped to nodes of other type. I was abble to implement this using BeforeDrop listener (I return false, when types are different). However I did not find any way to show user, that this drop operation is not allowed (no Over listener).
Could you suggest a way to solve this issue?
Best regards.
