I'm trying to implement the code from zilker (thanks, btw

), and till now I manage to display the categories horizontal in the head and to show the subcategories in the left menu, when a categorie is clicked.
So far so good...
But after clicking on a subcategorie the whole box with subcategories disappears. Like zilker I would like the box with subcategories to stay visible so a customer can choose another subcategorie without having to click again on the categorie.
I've tried to use the code provided by shan, but without any luck...
Could someone please be so kind to show how to do this?
Many thanks in advance!
