Thank you Amit5992. Very Nice solution!!

I’m using Yii2 Latest release 2.0.45 with bootstrap 4, so i have to change control-label to col-form-label in order to working.

form div.required label.col-form-label:after {
  content: " * ";
  color: red;

This can be handled at the layout - as opposed to each form.

Yii by default adds the “required” class to the fields that are required. See below:

<div class="form-group field-calcmortgage-loantype required">

With that already taken care of, what is left is defining the required class in the layout - see style section. I have added a special HTML character but you can simple add an asterisk if that’s all you desire. And once you do that, you never ever have to worry about marking required fields anymore (as long as you make sure the layout is customized).

    <meta charset="<?= Yii::$app->charset ?>">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <?php $this->registerCsrfMetaTags() ?>
    <title><?= Html::encode($this->title) ?></title>
    <?php $this->head() ?>
    .required:before { content:" \269D"; color:red;}
