How can I add placeholder text for the below captcha control?

The below is the code,




<?= $form->field($model, 'verifyCode')->widget(Captcha::className(), ['imageOptions'=>['style'=>'width:140px;height:50px;'] ] ) ?>

Try so:




<?= $form->field($model, 'verifyCode')->widget(Captcha::className(), ['imageOptions'=>['style'=>'width:140px;height:50px;'], 'options'=>['placeholder'=>'My text'] ] ) ?>

It worked, Thank you
