Can I render main view as well as partial in a single controller action?

Is it possible/how can I render two views within one controller action.

So for example I want my view action to render the index and then my _view partial which has content with a modal.

So that the modal will have the view content and then behind the overlay you’ll be able to see the listview thats within my index.php

Can’t you render the _view from within the view?

Just use

<?= $this->render('_overview') ?>

as mentioned in the doc.
