Question

css

I am using yii2 advanced.
There is a certain dropDownList on the form, indicated the output of certain values ​​​​in the dropDownList.
Now I can’t specify a specific style for it, how can I do it by analogy with:
<?= $form->field($model, 'typeRequest')->textInput(['style' => 'color:black; border -radius: 5px;', 'maxlength' => true]) ?> ?
