Thanks for answering but this isn't what I meant.
I know about tree sorting, not using it for this project though.
My question was about telling a droppable (or sortable if I would go
for your suggestion) what kind of elements to accept, and which not.
So for some folder (node) it's OK to receive a subfolder, but for
another it's not.
The rules as to what to accept can be more complex than just css class
names, so I was asking for a way around the standard 'accept' option
behavior on droppables (or sortables for that sake).
Thanks anyway :)
