Pages in the menu highlight nicely in blue when that page is selected. I also feature categories in the menu, however, and though they highlight grey on hover (as a page would), when the category archive 'page' is selected, the menu term doesn't highlight in the same blue colour as a page would. Is there some simple code I can add in to achieve this - and where would I add it? I have a couple of sub categories for each top category and I would also like the top category to highlight blue when the sub category page is selected.
Following on from that, I'd also like the category and sub category where relevant to show in the breadcrumb when a post is selected, and for the top category to be highlighted blue in the menu, when viewing a post relating to it.
