Whether to render and upload multiple files selected at once, together or separately.

Defaults to false, which means that when multiple files are selected in async mode, they will still be displayed and uploaded separately.

<input type="file" name="files" id="files" />

<script type="text/javascript">
    jQuery(function ($) {
            async: {
                enabled: true,
                batch: true,
                save: {
                    url: "/upload/save"
                remove: {
                    url: "/upload/remove"
