 * Menu displays a multi-level menu using nested HTML lists.
 *
 * The main property of Menu is {@see 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/new'],
 *             ['label' => 'Most Popular', 'url' => 'product/index/popular'],
