У меня так:
<?php
NavBar::begin([
'brandLabel' => Yii::$app->name,
'brandUrl' => Yii::$app->homeUrl,
'options' => [
'class' => 'navbar-default navbar-fixed-top',
],
]);
$menuItems = [
['label' => 'Обо мне', 'url' => ['/site/about']],
['label' => 'Контакты', 'url' => ['/site/contact']],
];
if (Yii::$app->user->isGuest) {
$menuItems[] = ['label' => 'Регистрация', 'url' => ['/site/signup']];
$menuItems[] = ['label' => 'Вход', 'url' => ['/site/login']];
} else {
$menuItems[] = ['label' => 'Выйти (' . Yii::$app->user->identity->username . ')', 'url' => ['/site/logout'], 'linkOptions' => ['data-method' => 'post']];
}
echo Nav::widget([
'options' => ['class' => 'navbar-nav navbar-right'],
'items' => $menuItems,
]);
NavBar::end();
?>
