register_taxonomy('genre', 'post', array('show_ui' => false));
Wordpress
register_taxonomy('genre', 'post', array('show_ui' => false));
ABecause the taxonomy name 'genre' is reserved and cannot be shown.
BBecause 'show_ui' is set to false, the taxonomy UI is hidden in admin.
CBecause 'show_ui' is missing, the taxonomy defaults to hidden.
DBecause 'show_in_menu' is false by default, it hides the taxonomy.
