Yii2 attributes??

Question

PHP

Good evening, how can I add an attribute to each data-lang element?

print $form->field($regModel, 'helps')->checkboxList([
                  '1' => Yii::t('content', $regModel->List['helps'][1]),
                  '2' => Yii::t('content', $regModel->List['helps'][2]),
                  '3' => Yii::t('content', $regModel->List['helps'][3]),
                  '4' => Yii::t('content', $regModel->List['helps'][4]),
], ['class' => 'btn-list mob-w100', 'onclick' => 'onInputClick(this, "checkbox")'])->label(false);
