Hi Michelle,
Just in case someone else checks this for a solution, I figured I'd post the response.
All that means is: make your menu data file, then take the main menu out of it, put that in the table cell where you want the menu inside script tags, then
The sub menus need to be built as HTML objects on their own and not be embedded inside any other HTML object.
means to put the call for the menu_data.js file along with the 3 other milonic files right after the body tag. This means that the milonic files including the menu_data file are all 'read' by the browser and the browser has all the submenu information before it reads the main menu.
