Trait yii\bootstrap\BootstrapWidgetTrait
BootstrapWidgetTrait is the trait, which provides basic for all bootstrap widgets features.
Note: class, which uses this trait must declare public field named options
with the array default value:
class MyWidget extends \yii\base\Widget
{
use BootstrapWidgetTrait;
public $options = [];
}
This field is not present in the trait in order to avoid possible PHP Fatal error on definition conflict.
