设置参数

    \'show_in_menu\'  => false

使用register\\u post\\u type（）注册帖子时，会忽略该帖子类型的管理菜单，因此这是隐藏菜单的最佳解决方案。

如果无法访问它，可以在admin\\u菜单上挂接一个函数，以添加或删除菜单和子菜单。

这里有一个例子。我们确实创建了一个“艺术家”帖子类型，但我们不需要艺术家管理菜单。我们想把它放在“音乐”菜单下；这将有其他各种子菜单。

    add_action( \'admin_menu\', \'adjust_admin_menu\' );

    function adjust_admin_menu(){

        $menu_slug = \'music\'; //menu slug (or path to file); as ID
        $post_type_artist_slug = \'artist\';
        $post_type_artist = get_post_type_object($post_type_artist_slug);

        /////Delete the menu generated by register_post_type() for our custom post type \'artist\'.  When registering a post type, setting 

        $remove_menu_slug = sprintf(\'edit.php?post_type=%s\',$post_type_artist_slug); //menu slug (here, a path to file); as ID

        //remove the menu
        remove_menu_page( $remove_menu_slug );
        /*
        //OR remove the \'add new\' submenu
        remove_submenu_page( 
             $remove_menu_slug,
            sprintf(\'post-new.php?post_type=%s\',$post_type_artist_slug) //SUBmenu slug (here, a path to file); as ID
        );
        */
        /////Create our custom menu

        $this->menu_page = add_menu_page( 
            __( \'Music\', \'music-plugin\' ), //page title - I never understood why this parameter is needed for.  Put what you like ?
            __( \'Music\', \'music-plugin\' ), //menu title
            \'manage_options\', //cappability
            $menu_slug,
            array($this,\'settings_page\'), //this function will output the content of the \'Music\' page.
            \'dashicons-album\', // an image would be \'plugins_url( \'myplugin/images/icon.png\' )\'; but for core icons, see https://developer.wordpress.org/resource/dashicons 
            6
        ); 

        ////Add submenus

         add_submenu_page(
                $menu_slug,
                $post_type_artist->labels->name, //page title - I never understood why this parameter is needed for.  Put what you like ?
                $post_type_artist->labels->name, //submenu title
                \'edit_posts\',
                sprintf(\'edit.php?post_type=%s\',$post_type_artist_slug) //SUBmenu slug (here, a path to a file); as ID

         );

         add_submenu_page(
                $menu_slug,
                $post_type_artist->labels->add_new_item,
