I am trying to replicate http://www.round.com.au/ menu system for organising it's work by using wordpress categories and posts but need some help.
I have got it to work so that when I am in a post the used categories highlight by adding a custom css class to them using this http://kahi.cz/wordpress/highlight-used-categories-plugin/
But I am not sure how to make it work so that when I am on a category page all the posts that are in that category not only display but are highlighted in the menu.
Thanks for your help. I am a young graphic designer trying to learn code so my php is minimal but CSS/html is good.
