Add layer to Megento Menu

This project has two parts. It is for the website here: shatterboxwebdesign [dot] com/roche/purse-styles [dot] html Both parts are changes to the menu. Part 1: Add another layer to the "All Styles" drop down. In the admin section add new categories under each of the "Styles". Under each style should be a selection of available sizes. Even if there is only one size for the style this should be listed. Example: Aztec - Small - Medium - Large Basia - Small Berkeley - Small - Medium Bodega In these new categories add the corresponding products. So if a user clicks on Aztec > Small, all of the small aztec bags should be shown. See the Aztec style for an example. Part 2: Make the third level menu items fade in. Right now if third level menu items are added they appear under the parent item (see Aztec bags for example). Make this menu fade in, when the user hovers over an item. See the attached image for an example. Please let me know if there are any questions about the project.
