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.
