/**
 * Menu displays a multi-level menu using nested HTML lists.
 *
 * The {@see Menu::items()} method 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
 * <?= Menu::Widget()
 *     ->items([
 *         ['label' => 'Login', 'link' => 'site/login', 'visible' => true],
 *     ]);
 * ?>
