This tree could be used in the WebLeftBar, for example. Clicking on the plus icon next to Webs will expand the subtree below that node.

To add "collapse/expand all nodes" functionalities do something like:

<a href="javascript: tree.openAll();">open all</a> | <a href="javascript: tree.closeAll();">close all</a>
