There is now an updated version of aqTree: check out aqTree2, which is better. Use that instead.
Sick of all that
menuLevel2 = addSubMenu("menutitle",subMenuObject1,"20px")
Well, worry no more! Now simply just add nested unordered lists to your pages and then use the amazing tree generator to turn them into tree structures!
This page contains two identical lists. The first is then converted into an expand/collapse menu, assuming that you have a browser with full DOM support. A little smattering of CSS to make it look pretty, and there you have it.
