Here's a newbie question

We don't have a lot of products, so I just want to bypass the subcategories and display the products directly under the main category. We have dropdown menus on the top bar, and when I associate some products directly with a main category, I want them to be listed in the menu, not the subcategories. For example... Assume I have 3 soaps: soap-a, soap-b, soap-c. I just want to have a "Soap" category, which includes these three soaps. When I hover the mouse on the "Soap" on the menu, I would like to see a dropdown menu that lists these soaps. However, since I don't have any subcategories, Soap menu item sits there (looking like a button with no dropdown menu), and you need to click it to reach the products.
Any ideas will be very much appreciated. Thanks in advance!
