Hello,

Only recently joined this list so apologies if I've missed anything (please
correct me if this is the case). I know it has a performance hit but
wouldn't it be better to implement a server-side solution? I am partially
sighted and use VERY large fonts and when site have layers or fixed line
heights they are unusable. A simple HTML list constructed dynamically would
do the job?

A little concerned I've missed the boat since only client-side scripting has
been mentioned?

Cheers
Ian

Check http://www.xs4all.nl/~ppk/js/
Site itself uses JS-based "collapsing" menus, in addition Peter-Paul Koch 
(author of that site) has many useful scripts.

as about "pages still need to be usable when scripts are turned off" 
 - you may want to put <A HREF="your link when JS is off" onclick=".. call
JS 
function to show page ...">
So with scripting turned Off user will get pre-defined page, while with JS 
available you can fine-tune new page.

Hope this helps.
