On www.hotelsupplies.us and other similar sites, one time one person click on the vertical nice_menu of the left I want to show him also the list of subterms, on the top of the page, in similar way of: http://www.alibaba.com/Fruit_pid103 for example here I clicked on FRUIT and then it purpose me on the top also subcategories like:
Fresh Fruit (119431) Dried Fruit (31940) Coconut Products (9693) Preserved Fruit (29474) Organic Fruit (31865) Canned Fruit (18135) Frozen Fruit (12952) Bananas (5992) Olives (2056) Berries (1835)
How I can do that with drupal or something similar?
