/**
 * NavBar renders a navbar HTML component.
 *
 * Any content enclosed between the {@see begin()} and {@see end()} calls of NavBar is treated as the content of the
 * navbar. You may use widgets such as {@see Nav} or {@see \Yiisoft\Widget\Menu} to build up such content. For example,
 *
 * ```php
 *    if ($user->getId() !== null) {
 *        $menuItems = [
 *            [
 *                'label' => 'About',
 *                'url' => '/about',
 *            ],
 *            [
 *                'label' => 'Contact',
 *                'url' => '/contact',
 *            ],
 *            [
 *                'label' => 'Logout' . ' ' . '(' . $user->getUsername() . ')',
 *                'url' => '/logout'

 * Note: $currentPath it must be injected from each controller to the main controller.
 *
 * SiteController.php
 *
