您可以拦截全局$submenu var并添加所需的元素：

add_action(\'admin_menu\', \'add_custom_submenus\', 999);

function add_custom_submenus() {
  global $submenu;
  $submenu[\'edit.php\'][] = array(
    __(\'Published\'), // menu title
    \'edit_posts\', // menu cap
    \'edit.php?post_status=publish&post_type=post\' // menu link
  );
  $submenu[\'edit.php\'][] = array(
    __(\'Scheduled\'),
    \'edit_posts\',
    \'edit.php?post_status=future&post_type=post\'
  );
  $submenu[\'upload.php\'][] = array(
    __(\'Unattached\'),
    \'upload_files\',
    \'upload.php?detached=1\'
  );
}
