Heirarchal Trees

Does anyone know where I can get/how I can make a free script that will handle explorer-style heirarchy? I've found one that works, but it requires reloading the page when a link is opened. My lovely altered version of it is shown here:

The reason I don't want it to refresh the page is because it will be calling on a script for the data, and that will mean huge times between clicking the [+] and it expanding. Is this even possible? Does anyone know a solution for this problem? I have a deadline on the page, so if anyone can help me out it would be greatly appreciated.

P.S. I only think it's possible having looked at deviantart.com, but it could be an illusion. ;)

View Source. You might also want to take a look at webmonkey.com as it appears they're using CSS to accomplish this.

I think they have a script like that at http://www.projectseven.com
