The only way to highlight a category when active would be to make the category the menu link as James suggests. In that way, when you're on the category, it should remain highlighted, but any subcategory will not do that. I don't think a post within the category will keep the menu highlighted either, only being on the category page itself.
To customize this, you'll need either a plugin (if it exists) or, one of our Pro developers to help you write specific code to accomplish your goal. Please see http://www.pagelines.com/pros.Go to the full post
