Simple tooltip menu show a tooltip submenu
Simple Tooltip Menu
This is a simple tooltip menu that will show a tooltip submenu when hovering over an item. The submenu will either appear above or below the main menu, depending on where more space is available. Using Modernizr's touch detection, the menu will either react on hover or on click. Example media queries show how to adjust the style for smaller screens.
