how to show subcategories?

Is there anybody who knows how to display three or more category layers on one page? See below the situation:

Category title (category level 1)

- subcategory title (category level 2)

- subcategory title from subcategory (category level 3) (how to display?)

Normally CS-Cart display the category level 1 and 2 automatic (views/categories/view.tpl).

How can you show the third level category on one page? I think more people want to show more category levels but i can’t find anything about it on the CS-Cart forum.

Thank you for your help.
