This should be straightforward regarding WP settings, however I don't see it yet:
I want every menu in my navigation to contain the posts from all my categories. But I also want every category to contain the posts from all my menus.
Menu: Reviews, News, Events
Category: Car, Computer, Home Improvement
When I click on menu "Reviews" I want to show posts containing reviews for all categories.
When I click on category "Car" I want to show posts containing all menus for the car category.
Thanks in advance & hope someone can help!
