flash gallery submenu

Hi - here is my gallery: [login to view URL] Basically I want a drop down menu added, like this example: [login to view URL] (hover over "STILLS" menu item) Here are the requirements for modifying my gallery. Please see attached graphic for illustration: FUNCTIONALITY: 1. When a user hovers mouse over the main PAGE menu and if there exists SUBPAGES then, dropdown automatically displays. User can then move mouse down and select one of the SUBPAGES for viewing. 2. When a user is viewing a SUBPAGE gallery, then the PAGE menu item is highlighted. 3. When a user clicks on the main PAGE menu item, then it automatically defaults to showing the first SUBPAGE listed in the XML list. COLORS: Drop down menu default: same XML color scheme as normal menu items. Mouse over: same XML color scheme as mouse over menu item. thanks! John
