注册分类法时，应使用此参数\'show_in_nav_menus\' => true, 为了使用WP菜单生成器中的分类术语。

例如：

register_taxonomy(
  \'videoCategories\',
  array(\'video\'),
  array(  \'labels\' => array(
      \'name\' => \'Video Categories\',
      \'singluar_name\' => \'Video Category\'
    ),
    \'public\' => true,
    \'show_in_nav_menus\' => true,
    \'show_ui\' => true,
    \'show_tagcloud\' => true,
    \'hierarchical\' => true,
    \'rewrite\' => array(\'slug\' => \'videos\', \'with_front\' => true)
  )
);
