删除顶级管理菜单：

    function custom_menu_page_removing() {
    remove_menu_page( $menu_slug );
}
add_action( \'admin_menu\', \'custom_menu_page_removing\' );

要仅删除某些菜单项，请仅包括要隐藏在函数中的菜单项。要仅删除特定用户的菜单，您可能需要使用current\\u user\\u can（）。

你可以看看https://codex.wordpress.org/Function_Reference/remove_menu_page

请您尝试一下：

$data = get_userdata( 1 ); // or any other ID where your new role works
if ( !empty( $data) ) {
    $user_caps = $data->allcaps;
    echo \'<pre>\' . print_r( $user_caps, true ) . \'</pre>\';
}

您将了解自己的能力。

然后使用以下代码简单地删除它们：

// Remove a capability from a specific user.
$user_id = // The ID of the user to remove the capability from.
$user = new WP_User( $user_id );
$user->remove_cap( \'read_private_posts\' );
