      * If you want to use a widget that does not have `model` and `attribute` properties,

+     * the following code, assuming that `$form` is your [[ActiveForm]] instance:
+     *
+     * ```php
+     * $form->field($model, 'date')->widget(\yii\widgets\MaskedInput::className(), [

      * @param string $class the widget class name
      * @param array $config name-value pairs that will be used to initialize the widget
      * @return static the field object itself
