Showing Custom Content in a Nav Dropdown

1. If i understand the question correct then you need this:

   add_filter('walker_nav_menu_start_el','auto_category_subMenu',10,4);
   function auto_category_subMenu($item_output, $item, $depth, $args){
       //first you check if the current item is a category
       if (!$item->object == 'category'){
           return $item_output;
       }else{
       //if it is a category then check that it is the right one.
           if ($item->title == 'Water Balloon'){
                  //if we got this far the we are on the parent menu item and
                  // we are going to get all of the balloon post type listed under it
               global $post;
               $tmp_post = $post;
               $args = array(
                   'post_type' => 'balloons',
                   'posts_per_page' => -1,
                   'category_name' => $item->title
               );
               $re = '';
               $submenu_items = get_posts( $args );
               foreach( $submenu_items as $post ){
                   setup_postdata($post);
                   $re .= '<li ><a href="'.get_permalink($post->ID).'">'.get_the_title($post->ID).'</a></li>';
               }
               $post = $tmp_post;
               return $item_output.'<ul>'.$re.'</ul>';
           }
       }
       return $item_output;
   }
   

   this code assumes that your category name is “Water Balloon” and your post type is named “balloons” if not simply change that.

2. It’s very likely you have some kind of collusion somewhere. Is it possible you have something like?

   register_post_type( 'balloon', $args ); and also register_taxonomy( 'balloon', array('balloon'), $args );

   Take a look at the code below. It’s a complete plugin. Compare this with your code.
