I am new to web design and development. I saw a mega menu on this site www.rackspace.co.uk. and love it after days of trying to develop it and lots of research I still can't get me head round how to do it. Does anyone have ideas for all your help is appreciated.



Its not a big deal buddy, If you know just how these menu of Daniweb works you can do that in any size. Its all done in CSS. Unfortunately I dont have time to give you exact solution. Checkout CSS files on both the sites. Else I am sure some other Daniweber will help you out.
If you are doing it commercially then just search CSS Menu. If you are student then learn the concept and then implement. Maybe I can reply you tomorrow. I hope till that time you will get a reply with CSS.

Google CSS hover menu bud, there are heaps of tutorials and free scripts online
