Mega Menu in WordPress

I finally made a Walker class for WordPress which allows me to use a Mega-Menu style menu. In wordpress menu editor I can add a CSS class of "break" to create a new column for sub-menu items. I can also add a CSS class of "widget" which then allows me to add any Widget in the Widget area and have it show up in the menu. I can add a class of "popular" to have the Popular tag show up as well. Just something I been playing with all day and have wanted to do for YEARS!
