+### Custom index of the row <a id="custom-index"></a>

+Assume that you want to set specific index for each row. In this case you can pass the `data` attribute as associative array
+as in the example below:
+
+```php
+    <?= $form->field($model, 'field')->widget(MultipleInput::className(), [
+            'allowEmptyList' => false,
+            'data' => [
