SliderInput renders a slider jQuery UI widget that writes its value into hidden input.

For example,

echo SliderInput::widget([
    'model' => $model,
    'attribute' => 'amount',
    'clientOptions' => [
        'min' => 1,
        'max' => 10,
    ],
]);

The following example will use the name property instead:

echo SliderInput::widget([
    'name' => 'amount',
    'clientOptions' => [
        'min' => 1,
        'max' => 10,
    ],
]);

You can also use this widget in an yii\widgets\ActiveForm using the yii\widgets\ActiveField::widget() method, for example like this:

<?= $form->field($model, 'from_date')->widget(\yii\jui\SliderInput::classname(), [
    'clientOptions' => [
        'min' => 1,
        'max' => 10,
    ],
]) ?>
