* Menu displays a multi-level menu using nested HTML lists.
*
* The main property of Menu is [[items]], which specifies the possible items in the menu.
* A menu item can contain sub-items which specify the sub-menu under that menu item.
*
* Menu checks the current route and request parameters to toggle certain menu items
* with active state.
*
* Note that Menu only renders the HTML tags about the menu. It does not do any styling.
* You are responsible to provide CSS styles to make it look like a real menu.
*
* The following example shows how to use Menu:
*
* ```php
* echo Menu::widget([
* 'items' => [
* // Important: you need to specify url as 'controller/action',
* // not just as 'controller' even if default action is used.
* ['label' => 'Home', 'url' => ['site/index']],
* // 'Products' menu item will be selected as long as the route is 'product/index'
* ['label' => 'Products', 'url' => ['product/index'], 'items' => [
* ['label' => 'New Arrivals', 'url' => ['product/index', 'tag' => 'new']],
* ['label' => 'Most Popular', 'url' => ['product/index', 'tag' => 'popular']],
* ]],
* ['label' => 'Login', 'url' => ['site/login'], 'visible' => Yii::$app->user->isGuest],
* ],
