Tree menu in sidebox

Hello David,

I created a sidebox with this topic http://www.pricetapestry.com/node/5821.

Now i tried to add a tree menu in it with some scripts i found.

I want to add manually link/categories like this:

But als have the option to add the maincategory with sub and subsub categories.

Also i want that the site remembers with category is collapsed with a cookie.

I found a really nice one but i can't get it to work.

{link saved}

Or do you maybe have another script for me?

Thanks Jan Roel
