1) Script Title: Simple Tree Menu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex1/navigate1.htm

3) Describe problem: I have 3 trees and can only get a single tree to auto expand. Does not matter which tree I choose it will only ever auto expand one tree. The only way I can get any menu to auto expand is by using a simple body onload:
<body onload="javascript:ddtreemenu.flatten('treemenu1','expand')">

Show/Hide all work fine but I cannot get the trees to auto expand. Any ideas?

IE9 but was happening on 8 as well. I have tried the rel="open" but tono avail.
