One note... although this menu system works well in all browsers tested, you will likely have problems in Admin Mode if using Internet Explorer. There seems to be no problems with the admin tools using any other browser. I am unable to test with IE, not having a windows machine. If someone else works out the css bug(s) for the admin tools in IE, please PM me.
Instructions are in the readme file. Although not really difficult to implement, you should read the readme :)

Add the following to the top
You may need to tweak the - value in the first top statement to suit your layout, but the idea is to get the pop-up tools out from under next menu item, where IE renders it.
hmmm. I can't seem to get it to display here. Please see this post for the code..
