 * InputWidget is the base class for widgets extending the [[YiiInputWidget]] that collect user inputs in all

 *
 * An input widget can be associated with a data model and an attribute, or a name and a value. If the former, the
 * name and the value will be generated automatically.
 *
 * Classes extending from this widget can be used in an [[\yii\widgets\ActiveForm|ActiveForm]] using the
 * [[\yii\widgets\ActiveField::widget()|widget()]] method. For example like this:
 *
 * ```php
 * <?= $form->field($model, 'from_date')->widget('WidgetClassName', [
 *     // configure additional widget properties here
 * ]) ?>
