I'm newbie on Wordpress. Currently I'm developing a blog using Wordpress 3.3. For now I have 4 main article categories Javascript, Gammu, PHP and Oracle. I have put all of these categorie in the main menu. You can check it on [Programming Tutorial](http://www.semurjengkol.com)

My question is: can I have a single dropdown menu called category and if the user move the cursor over it, all categories would be listed?
