Hi,
I have a page with 3 frames:

frame1: loads top_nav.html
frame2: loads left_nav.html
frame3: loads content.html

In most cases, a menu from the top_nav will load a left_nav and a content, but for some menus, a FULL width content page will show (in other words, no left nav). How can I get rid of the left_nav for full pages? Is there a way to fake it, like laying a div over the left_nav and content areas so that these 2 frames/areas look like only 1 content page is showing (if so, where could I put the div and how do I hide/display it)?

If know of a script or solution out there already, greatly appreciate your help.
