I'm trying to get my navigation to have all the right highlighting (current-nav-menu), but I can't get a couple pages. I've got a project index and single-project pages. I've got it working on the single-projecst through the use of the is_singular('portfolio') function and some extra css in the head. I can't seem to find a way to even know when the project index is even being loaded, aside from maybe just using some regex and testing the url...
Any ideas? Many thanks.
