I've written an expanding and collapsing navigation menu for my website. I'm using <div>s for the submenus and changing the style.visibility and style.display properties to show and hide them. The problem I have is the different behaviour between browsers. It works OK in MSIE but in NS6 when you hide the submenu it leaves a huge gap where the menu was, rather than realigning the menu. You can see what I mean here
. I think the problem could be something to do with Netscape's treatment of tables, but I'm not sure how to change it. If you have any suggestions I'd be very pleased to hear them.
