While not EXACTLY what you outlined, I've used TreeView http:www.treeview.net along with Python to create the dynamic tree menus you describe. I had to write a couple or very short JavaScript additions, but it is working just fine. All the tree opening and closing is done on the client via-javascript so it is very fast.

Hi,
Before I reinvent the wheel I`d like to ask if someone has done this before since I did not find an advice at Google.
The goal is to create a dynamic Tree View in HTML.
Say I have a data strucure like this:
structList = {'Sun':{'Sun.1':['Sun1.1','Sun1.2'],'Sun.2':['Sun2.1','Sun2.2']},'Kupa':['Kupa1']}
I want to transform this into HTML:
<ol> <li><a href="?a=Sun">Sun</a></li> <ol> <li><a href="?a=Sun.1">Sun.1</a></li> <ol> <li><a href="?a=Sun1.1">Sun1.1</a></li> <li><a href="?a=Sun1.2">Sun1.2</a></li> </ol> <li><a href="?Sun.2">Sun.2</a></li> <ol> <li><a href="?a=Sun2.1">Sun2.1</a></li> <li><a href="?a=Sun2.2">Sun2.2</a></li> </ol> </ol> <li><a href="?a=Kupa">Kupa</a></li> <ol> <li><a href="?a=Kupa1">Kupa1</a></li> </ol> </ol>
If the user clicks on a branch-link say 'Sun.1' then the branch below opens/closes (not printed by the servlet). Like a tree view control in an native GUI app.
Has this, or a similar approach, been done before in python ( I am using webware/cheetah)?
