您可以创建一个插件来更改管理仪表板。您只需创建两个函数，一个用于更改顶层工具栏，一个用于更改侧栏。然后您可以添加一些css来设置它们的样式，这将使您朝着正确的方向前进。

 // If you want to change top level admin/toolbar bar
 add_action( \'wp_before_admin_bar_render\', \'my_admin_bar_render\' );

 function my_admin_bar_render() {
   global $wp_admin_bar;
   // remove all top level toolbar items
   foreach ($wp_admin_bar->get_nodes() as $node) {
     $wp_admin_bar->remove_node($node->id);
   }
   $wp_admin_bar->add_menu( array(
     \'parent\' => false,
     \'id\' => \'my-logo\',
     \'title\' => \'<img src="http://example.com/logo.png" alt="Blavatar" class="blavatar" height="16" width="16">\',
     \'href\' => "http://example.com"
   ));
   $wp_admin_bar->add_menu( array(
     \'parent\' => false,
     \'id\' => \'my-toolbar-1\',
     \'title\' => \'Some toolbar item\',
     \'href\' => "http://example.com"
   ));
}
// If you want to change the side bar
 add_action( \'admin_menu\', \'my_admin_menu\' );
 function my_admin_menu() {
   global $menu;
   $menu = array(
     array(
       \'My menu one\',
       \'\',
       \'http://example.com\',
       \'\',
       \'my-menu-class\',
       \'\',
       \'div\'
     )
  );
}
