# Post template based on categories

 * I have successfully
 * 1. Created a page displaying posts on a category
    2. Created a custom field to
   display menu based on that page
 * But when I click on a post of that category, the menu comes back to the default
   one.
 * What I try to achieve is, all posts in that category and subcategories will show
   the menu that I designed for the category and subs. Should I use conditional 
   tags or something?
 * Any help is appreciated…

 * Yes, conditional tag [in_category()](http://codex.wordpress.org/Function_Reference/in_category)
   is a variant to use.

 * Thanks… I will try that. Is there any way to declare the category and its subcategories?
   Adding numbers is hard

       $special_cats[] = 1; // 1 is ID of parent cat
       $args = array(
           'child_of' => $special_cats[0];
       );
       $categories = get_categories($args);
       foreach($categories as $category) {
           $special_cats[] = $category->cat_ID;
       }
       (in_category($special_cats) || is_category($special_cats)) ? $theme_location = 'special' : $theme_location = 'default';
       wp_nav_menu(array(
           'theme_location' => $theme_location
       ));
       ```
