38927 oscommerce - dropdown menu

I need two categories to have drop down menus (for the subcategories) and to include the manufacturer/brand name for each category. eg: Men's category has subcategories Tees, Pants, Hats. Tees, Pants and Hats should be in a dropdown menu. There are different Brands offered under each subcategory, such as Brand 1, 2, 3 and 4. Brands 1, 2, 3,4 to be included as well in the dropdown menu.
