Class yii\bootstrap4\NavBar
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 yii\bootstrap4\Nav or yii\widgets\Menu to build up such content. For example,
use yii\bootstrap4\NavBar;
use yii\bootstrap4\Nav;
NavBar::begin(['brandLabel' => 'NavBar Test']);
echo Nav::widget([
'items' => [
['label' => 'Home', 'url' => ['/site/index']],
['label' => 'About', 'url' => ['/site/about']],
],
'options' => ['class' => 'navbar-nav'],
]);
NavBar::end();
