Currently dropdown menus are built in ...Site Settings > Modify Navigation Site Navigation Settings (AreaNavigationSettings.aspx). I would like to be able to modify the Navigation editng and sorting section to do the multiple submenus (flyouts).
I would like for the dropdown menu items to have more then one level of menu. I would like to be able to add submenus. How can I do this

Not sure if you're talking about the quicklaunch menu or the top navigation bar, I am assuming its the latter.
These two links should be of help if that is the case

In case you need to increase the number of dynamic levels: http://www.sharepointblogs.com/gnarus/archive/2006/11/01/15638.aspx
