suggestions with structured data #193

Hello,

in our Database we do have data saved as a tree. So each Child has a parent.
A
--AA
--AB
B
--BA
--BB

In our case it would be useful to show the user the tree in the combox dropdown. Because it could be possible that leaves have the same name like:

project A
--todo
--finished
project B
--todo
--finished

Is there any way or idea to display the tree with a Django Selectable widget?
