[ic] 3-level category tree

[Lukasz Z]

Hi everyone!

I've been wondering how to build a 3-level category tree using area/category
tables layout from "foundation" store.
To give you a specific example of what I need (for the sportsman inside of
you;):

level    (1)       (2)            (3)
/
|----- skiing
|            |
|            |------skis
|            |           |
|            |           --------carving
|            |           --------racing
|            |           --------kids
|            |           --------etc
|            |
|            |
|            |------boots
|            |            |
|            |            |--------men's
|            |            |--------women's
|            |            |--------kids
|
|------tennis
|            |
|            |------rackets
|            |            |
|            |            |-------beginner
|            |            |-------master
|            |            |-------etc

Best if "sking" or "tennis" would open a new page (main page for a level 1
category), and "skis" (level 2) or "racing" (level 3) would just trigger a
search.

How to achieve this result without loosing functionality from foundation
admin? (I'm aware - I can build a new table for categories, but that's not
what I'm looking for as for now ;)
