add_action('admin_bar_menu', 'add_toolbar_items', 100);
function add_toolbar_items($admin_bar){

    $admin_bar->add_menu( array(
        'id'    => $menu_id,
        'title' => '<span class="ab-icon dashicons-before dashicons-admin-generic"></span> Barfia setting',
        'href'  => get_admin_url().'admin.php?page=barfia-setting',
        'meta'  => array(
            'title' => __('Barfia setting'),            
        ),
