I implemented a tree using CSS/Javascript with the methodology outlined
here:

You could achieve what your are trying to do using that.
To 'ajaxify' it, and load nodes on demand you could try adding a wicket
AjaxLink around your branch div, and have that replace a target
component in your Panel that holds all the <div> elements for tree nodes
that have been loaded. Then the regular javascript call would make the
nodes visible for the branch item just clicked.
Question might be what order the calls are made - showbranch or load new
divs, if showBranch comes first you'd need to workaround.

Hi, how far away is Wicket from being able to do this:
- create a tree object initially displaying only the root node
- when you click to expand a node do it via a xmlhttprequest to the server
- the server responds with just the children which are inserted into the
DOM rather than the entire page or entire tree object being redrawn
and as an optional nice-to-have:
- preload the children as hidden elements and have an expand operation
use javascript to make the children visible locally (no roundtrip delay)
whilst meanwhile calling the server to add new hidden grandchildren in
the background.
Thanks,
Dave
