yii2顶部导航使用

yii2中使用顶部导航的具体方法：

1.视图中调用两个类：

use yii\bootstrap\Nav;
use yii\bootstrap\NavBar;

2. <?php
NavBar::begin([
'brandLabel' => 'My Company',
'brandUrl' => Yii::$app->homeUrl,
'options' => [
'class' => 'navbar-inverse navbar-fixed-top',
],
]);
$menuItems = [
['label' => 'Home', 'url' => ['/site/index']],
['label'=>'注册','url'=>['/manager/register']],
['label'=>'关于我们','url'=>['/site/about']],
];
if (Yii::$app->user->isGuest) {
$menuItems[] = ['label' => 'Login', 'url' => ['/site/login']];
} else {
$menuItems[] = [
'label' => 'Logout (' . Yii::$app->user->identity->username . ')',
'url' => ['/site/logout'],
'linkOptions' => ['data-method' => 'post']
];
}

echo Nav::widget([
'options' => ['class' => 'navbar-nav navbar-right'],
'items' => $menuItems,
]);
NavBar::end();
?>

效果如下图：
