The last menu item's dropdown in the Main Menu seems to be coded incorrectly, or at least doesn't function. Looking at the code, working dropdown menus have <div ...><ul ...><li ...><ul ...><li ....> whereas the broken one has <div ...><ul ...><li ...><ul ...><span ...>. It's the only dropdown coded that way and the only one not working.
The menu item in question is at
www.rompsites.net/mvhh, menu item "Home Ownership"'s dropdown links.
Thanks!
