I'm trying to create a navigation menu that is a table of 4x5 boxes. The top 4 should have radio-style behavior that brings up a different set of 16 boxes below it when clicked. I'm also trying to have a default set of boxes that display pictures when the page first initiates and no boxes are yet selected AND when a box is de-selected. Lastly, I'd need for another table to display once an actually link (of the 16) is selected. I've given this my best attempt over the past few days, but I'm getting nowhere fast. Any help would be majorly appreciated. Thanks.
