Does anyone know if it is possible to only show the child categories when the parent categories have been clicked.

For example have the category sidebary normally showing:
Full Tilt Poker
Poker Stars

then when Full Tilt is clicked showing:

Full Tilt Poker
Review
Promotions
Etc.
PokerStars

So it would bring up all the Full Tilt posts, but then you can further specify by choosing a child category.

Any help would be appreciated, I couldn't find the answer from searching wordpress forums.
