[
    [
        'label' => $menu['name'], 
        'url' => [$menu['route']],
        'items' => [
			[
				'label' => $menu['name'], 
				'url' => [$menu['route']]
            ],
            ....

        'label' => $menu['name'], 
        'url' => [$menu['route']],
        'options' => $data,
        'items' => $menu['children']
    ];
}

$items = MenuHelper::getAssignedMenu(Yii::$app->user->id, null, $callback);
