Multiselect rendered as tags in documents

In dataobjecs we have the possibility to render multiselects as tags. Is it possible to achieve the same functionality in documents? We have tried the following but nothing seems to change:

<?= $this->multiselect($filter, [ "width" => 200, "height" => 150, 'renderType' => 'tags', "store" => \InteliveBundle\Model\Utils::getSelectOptions($filter), "reload" => false, 'class' => "editmode-cssid", 'htmlspecialchars' => false, ]); ?>

This is not implemented but we can create improvement on github.
