How do I hide sub menus in Dreamweaver CS5.5?

Question

Hi - I'm at the very beginning of sorting out my first web site in Dreamweaver CS5.5. I'm using a vertical menu with sub menus. The submenus are permanently visible. I was earlier able to make them only appear when you roll over them with a mouse...but the sub menus then stuck way out into the next column. 
What I'd like is to have submenus that are hidden until you roll over them with a mouse. I'd like the submenus to be indented slightly from the main menu (like they are now, except that they're not hidden right now).
I seem to have changed a preference in Dreamweaver, because now when I delete the vertical menu and start all over again, I end up with the same formatting in my new menu. I can no longer end up with a hidden submenu items at all when I insert a vertical menu. I can create a horizontal menu with hidden submenu items, however, so I don't think I've changed the preference related to horizontal menus.
Thanks so much for your help with this!

Hi,
in addition to gramp's hint, you could have a look here. You could e.g. use directly (Google) or download and integrate into your DW files.:

On the other hand you can find some more by using Google itself, individually specific to your requirements and your preferences.
