Rails spinoffs - Aug 2005 - getting rid of dropped droppables

I need to allow the user to move items from one to another div (it
seems like it should be simple). If I set :revert => true on the
droppable then the item flys back even when the drop is successful. If
I set it to false it almost works as I need, but the droppable sits on
screen even after my div is updated. I want it to not exist in the
originating div and to be present in the target div (without the
dragged item hanging around). Any clue what I''m missing?

Thanks!
Tom
