InputWidget is the base class for widgets that collect user inputs.

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 ActiveForm using the widget() method, for example like this:

<?= $form->field($model, 'from_date')->widget('WidgetClassName', [
    // configure additional widget properties here
]) ?>

For more details and usage information on InputWidget, see the guide article on forms.
