CSS3 Dropdown Menu

Currently at [login to view URL] we are using infinite menus to create the left hand navigation. This program adds a bunch of junk code for it's licensing etc. that I want to eliminate. I am looking for the exact same left hand navigation to be recreated in CSS3 without the junk code. I have purchased the code at [login to view URL], which I want to use as a model so the code is clean. I have attached a screen shot of the current flyout menu and a sample that the mega drop down menu produces. I can give the code I purchased to the winning bidder if that would help you if you don't already know how to do it. So basically I am looking for the code at [login to view URL] to be cleaned up and incorporate the new CSS3 menu. Since this code is used on every page of the site I would need instructions on how to convert all the pages over. Please include a sample of a similar menu system you have coded.
