Re: Javascript fallbacks for drop down menus

Hi David,
If I may interject - I strongly recommend that pull-down menus (scripted or 
CSS) are avoided at all costs. Partially sighted users with Zoom find that 
the menu fills the whole screen (and more). As they cursor down the list 
they do not know when they have reached the last item of the menu. As a 
result the focus goes below the menu box and leaves them in the middle of 
your page !!!!!

A second concern is that drop-down menus encourage designers to include too 
many links on a single page. As these usually occur in HTML before the 
content it makes it very hard for users of screen readers who have to wade 
through hundreds of irrelevant links to find something of interest. The 
place for lots of links is the site map (or section maps). Individual pages 
should only have the basic "top level" links and the submenu of links 
relevant to the page content.

If, however, a pull-down menu is required I suggest that you use a form 
<select> element which is much easier for users to control (and takes up 
less page space when is use.

I'd say that's the wrong way around. Make sure the menu, ie. the list of 
is accessible, then apply the JS. The "old way", in other words.

Now, I don't know the background for this discussion, but:

The longdesc attribute does not provide an *alternative* for the image, but
rather a verbose *description* of it - in a hyperlinked document.
