‘taxonomies’ => array(‘category’), <========= add this….

‘public’ => true,
‘show_ui’ => true,
‘exclude_from_search’ => true,
‘hierarchical’ => true,
‘supports’ => array( ‘title’, ‘editor’, ‘thumbnail’ ),
‘query_var’ => true
)
);

hi mate thanks for the reply but i’m not sure if im applying this right, you add ‘taxonomies’ => category or the taxonomy name ?

i did this but no result, the taxonomies dont appear in the menu selected. see below for code:

$args = array_merge(
                  // Default
                  array(
                  'label' => $plural,
                  'labels' => $labels,
                  'taxonomies' => array('category'),
                  'public' => true,
                  'exclude_from_search' => true,
                  'query_var' => true,
                  'show_ui' => true,
                  'supports' => array('title', 'editor'),
                  'show_in_menu' => 'marketdisplayoptions',
                  'show_in_nav_menus' => true,
                  '_builtin' => false,
                  ),
                  // Given args
                  $this->post_type_args
          );

          // Register the post type
          register_post_type($this->post_type_name, $args);
