I tried the collapsible menu on a vertical menu I was working on. When I click on the menu, I get a JS error "Invalid Argument".
Even in the internal preview, it says error on line 881 (Menu.style.width = parseInt(dmbtbF[Menu.ptb].width) - 2*(parseInt(Menu.style.left) - parseInt(dmbtbF[Menu.ptb].left)) + 2*tbBorder[Menu.ptb]
Has anyone seen this before?
