Subcategories

Hey guys,

I am looking all over action theme options and everything else, but cant really figure out how to make it. OK so the deal is, I need to show on parent category his subcategories with listing count in it, like a small list(like a meniu or smth). And when user goes in deeper the same procedure goes on and on till there are no more subcategories and there is only listings. Anyone can give any suggestions about this?
