Help with simple tree menu

[GnL]

Script: Simple Tree Menu
http://www.dynamicdrive.com/dynamicindex1/navigate1.htm

Currently this script keep all levels of the menu expanded. Is there a way to have the clicked item expanded (just as it is now) but at the same time contract the rest?

Best regards

Mats

Edit: Nevermind. I came up with a solution myself.
