您可以通过以下代码重新订购管理左菜单：

/*
 * Code below groups Dashboard/Posts/Pages/Comments together at the top of the dashboard menu.
 * If you were to have a custom type that you want to add to the group use the following edit.php?post_type=YOURPOSTTYPENAME
 */
function reorder_my_admin_menu( $__return_true ) {
    return array(
         \'index.php\', // Dashboard
         \'edit.php?post_type=page\', // Pages 
         \'edit.php\', // Posts
         \'upload.php\', // Media
         \'themes.php\', // Appearance
         \'separator1\', // --Space--
         \'edit-comments.php\', // Comments 
         \'users.php\', // Users
         \'separator2\', // --Space--
         \'plugins.php\', // Plugins
         \'tools.php\', // Tools
         \'options-general.php\', // Settings
   );
}
add_filter( \'custom_menu_order\', \'reorder_my_admin_menu\' );
add_filter( \'menu_order\', \'reorder_my_admin_menu\' ); 

您可以使用管理菜单顺序插件。有几个，this one 是其中之一。

此外，这些不是“帖子”，而是后端面板菜单项。
