hi i was wondering if there was anyway possible to make the mootools tab script(the one that transitions with easing effects instead of going on to a different page) go on the top menu to a page that looks like the screenshot of puntovista on this site:

what i mean is by tabbing the menu on top but when you click one of the tabs it transitions only the "main" content as shown on the right of the screenshot
