I am looking at implementing the mootools accordion style menu on a site and wondered if anyone new whether it can be adapted to support persist menu states across the site.

I would like, when navigating through a site to ensure that the menu stayed open at the same category until a different category was clicked.

I have found many examples of sites demonstrating the mootools accordion, but none using it for menus with site links etc. If anyone knows of any such examples I would be glad to be pointed to these.
