There is no built-in support for this. If you want dynamic menus you would
use the insert html code fragment feature to insert code for your custom
menu/navigation bar. You can google for "dhtml menus", "JavaScript menus",
drop down or fly out menus and find a lot of freebie code snippets to
experiment with.
www.dynamicdrive.com is one source of such code.
