Yii 2 has a slightly different approach from Yii 1.x when it comes to rendering views inside views (or partials views).
Remember that, in Yii 2,
$this in a view refers to a
View object (not a controller) and it just so happens that Class View also has a render method and you can call it in your view, nesting views indefinitely.
<?php //this is a view file $this->title = 'ze Title'; ?> <div class="bar baz"> <!-- just like you would in a controller --> <?= $this->render( 'other_view', ['param'=> $some_var] ); ?> </div>
