How to insert nodes within treeview in an empty node with Drag & Drop

[haexhub]

Hi
I really love your css framework.
I would like to use the treeview component with drag & drop functionality, but I have a problem with inserting nodes into an empty node (directory).
How can this be achieved?
For example at your nested demo
One can always drag&drop the nodes in other nodes (directories) until you try to insert them in a node (directory) where no child nodes exist.
