Where does it set the layout in a basic YII2 application?

Question

Yii

I understand Yii2, I downloaded the basic application. Views have layout main.php which is shown on all pages. Where is it asked? Neither in configs nor in controllers is there anything like layout=main

Answer 1

It can be overridden in many places, for example in an action:
Here are the docs on the topic: www.yiiframework.com/doc-2.0/guide-structure-views...

Answer 2

main comes by default, you can set your own by passing $this->layout = 'yourLayout';

Answer 3

main.php is the default layer used by the application if it is not set in the config or controller. Respectively set in Yii components
