raphael menu

Hello, I am working on transitioning my site from the Dali theme to the Raphael theme, but can't find where the options are to create a rich sub-menu from the main navigation. How do I go about building that? Second question, how can I center the main nav (and utility nav)?

Hello, how can I show most popular items in my menu (Homepage Products in category menu)? I have tried editing my category menus. But the items aren't shown unlike in the raphael's demo site. What should I do? Thanks for you help!
