### Attaching behaviors from config
One can attach a behavior to a component when configuring it with a configuration array. The syntax is like the
following:
```php
return [
// ...
'components' => [
'myComponent' => [
// ...
'as tree' => [
'class' => 'Tree',
'root' => 0,
],
],
],
];
```
In the config above `as tree` stands for attaching a behavior named `tree`, and the array will be passed to [[\Yii::createObject()]]
to create the behavior object.
