lainyrache on "printCustommenu - active state"

I have custom links on my menu to /directory/album/subalbum/#thumbs
(linking to an internal page with javascript toggle. )
I want an active state on my custom menu links but they don't appear with the likes of
<?php printCustomMenu('top1','list','',"menu-active","submenu","menu-active",2); ?>
The custom link is probably meant for an external link. Can anyone guide me on another quick route?
thanks
