# Multiple Post Categories PLUS Parent Categories

 * I have a site where there are events that have categories attached to them. I
   want to be able to filter the events by the categories by using the slugs as 
   CSS classes. Problem is the filter is limited to top-level categories and events
   can have multiple categories attached to them.
 * For instance, the categories could look like this:
 * –Dance
    –Music —-Pop —-Rock –Theatre
 * What I’m aiming for is to be able to handle it if a user selected “Dance” and“
   Rock” and have the CSS classes of “category-dance”, “category-rock”, AND “category-
   music”.
 * The `post_class()` does fine for getting the multiple categories taken care of(
   showing “category-dance” and “category-rock”), but I’m struggling to figure out
   how to add the top-level parent category (“category-music”) to the list.
 * I’m sorry, but the site is currently in a dev environment and not publicly accessible.
   🙁
 * Do you have any suggestions that might help?

 * Hi. Its not a solution but could be a hint, I hope.
 *     ```
       <?php
         $catobj = get_category_by_slug( 'rock' );// get category slug somehow
         $parent_id = $catobj->category_parent;
         if ( !empty($parent_id) ){// when parent category exists
           $parentname = get_the_category_by_ID( $parent_id );
           var_dump($parentobj);
         }
       ?>
       ```
