I\'ve setup a menu for a fairly simple site based on icant.co.uk. It\'s fairly simple with maybe 5 pages. The small site is mainly a mysql browser for a few tables using MATE.
Here's a snippet from a project of mine. It it old ugly code, and uses tables, but you can just as easily use the idea for divs and cleaner markup. The trick is to make the navigation use a different class if the current page matches it's url.
