Question

You could, for example, create your own super controller and add a menuItems attribute :

namespace app\components;

class Controller extends \yii\web\Controller
{
    public $menuItems = [
        ['label' => 'Home', 'url' => ['/site/index']],
        ['label' => 'About', 'url' => ['/site/about']]
    ];
}

Your controllers should extend it :

namespace app\controllers;

use app\components\Controller;

class MyController extends Controller {...}

And in your layout :

echo Nav::widget([
    'options' => ['class' => 'navbar-nav navbar-right'],
    'items' => Yii::$app->controller->menuItems,
]);
