Yii: How to add inline style to select option item?

I have select HTML tag generated by this code:

<?= $form->field($model, 'something')->dropDownList(Class::method(), 
  ['prompt' => Yii::t('app', '--- Choose ---')]) ?>

JavaScript
​x
 
<?= $form->field($model, 'something')->dropDownList(Class::method(),   ['prompt' => Yii::t('app', '--- Choose ---')]) ?>​

I would need to add an HTML attribute (e.g. inline style) to each option tag.

Can you give me a hint, please?

Answer

You can use options

  <?= $form->field($model, 'something')->dropDownList(Class::method(), 
   ['prompt' => Yii::t('app', '--- Choose ---'), 
     'options' => ['value1' => ['style' => 'color:red;'],]]) ?>

JavaScript
 
  <?= $form->field($model, 'something')->dropDownList(Class::method(),    ['prompt' => Yii::t('app', '--- Choose ---'),      'options' => ['value1' => ['style' => 'color:red;'],]]) ?>​
