AR View Decorator Pattern

For example, you have a status attribute in your model, and you want always to display the status with a green o red light.

One use of the decorator pattern is to implement method to "decorate" some attributes, for example:

class AccountDecorator extends Account


public function getStatus()


    return "<i class="fa fa-circle '.($this->status?"green-class":"red-class"). ' "></i>";



My question is about more complex blocks of HTML, I don’t feel confortable with contacting everthing into a variable and returning it.

How can be done in Yii2?

$classes = ['fa', 'fa-circle'];

$classes[] = $this->status? 'green-class' : 'red-class';

echo Html::tag('i', '', ['class' => $classes]);
