/**
 * NavBar renders a navbar HTML component.
 *
 * Any content enclosed between the [[begin()]] and [[end()]] calls of NavBar
 * is treated as the content of the navbar. You may use widgets such as [[Nav]]
 * or [[\yii\widgets\Menu]] to build up such content. For example,
 *
 * ```php
 * use yii\uikit\NavBar;
 * use yii\uikit\Nav;
 *
 * NavBar::begin();
 * echo Nav::widget([
 *     'items' => [
 *         ['label' => 'Home', 'url' => ['/site/index']],
 *         ['label' => 'About', 'url' => ['/site/about']],
 *     ],
 * ]);
 * NavBar::end();
 * ```
