UI droppable could work much better? It often doesn't work
There is a problem with having the draggables different sizes with droppable.
I couldn't get
http://forum.jquery.com/topic/problems-with-drag-drop-of-different-sizes working with droppable.
But with 4 lines of code.. I can drag and drop correctly using hover and mouseup.
http://jsfiddle.net/Yz9V3/111/Why doesn't droppable use hover and mouseup on the target? I can't begin to guess what it's doing that makes it mess up so badly with different sized draggables.
Seems there might be an issue with negative margins too.
