FoldOut Menu

[jys]

Hi,
I would like to use the script bellow but is it possible to change it? When I open a page that is in a sub-categorie, the menu should start opened in the right categorie. How do I do that? I am a newbie and all what I tried did not work...
In advance, thank you for your help!
Yours,
Jys

Here is the code I use:
