Is it possible to highlight current section of the site in the menu?
Just link different menu_items.js files to different pages. Each local menu tree should have current item highlighted. It is also possible to write the wrapper comparing current URL with the link and highlighting items accordingly. Another way is to generate menu tree dynamically with the server side script (menu_items.asp or menu_items.cgi) that receives section name or id and modifies coloring parameters for items accordingly.
