Treeview and listbox or dropdownlist

[Sandra Castellanos]

Hi

Does anybody know how to make a listbox or dropdownlist formatted like a
treeview?
Or to make the treeview have the functionality of these?
Say I have the following tree:

Books
For Children
Cooking
Desserts
Soups
DVD
Action
Comedy
Drama
Music
Jazz
Latin
Classic
Rock

I want people to be able to search for one or more of the nodes of the tree,
and I want it to be easy to view. People must be able to expand or collaplse
the nodes, because the tree has just too many rows.

If anybody can give me an idea on how to do this, it'll be a lot of help

Regards,

SC
