Used to specify whether to use to fill the form fields. In order for this functionality to work, please if you are interested in getting your URL(s) added to the allowed domains list.
Note: databag is the legacy name for ActionProfile, hence the attribute/name mismatch.
nobody- disable this functionality
everybody- Allow pre-filling of information from any site in the ActionProfile network. Also requires sharing pre-fill data with other sites in the network.
Example, to enable the ActionProfile filling (assuming the site on which this tag is sitting has been allowed):
<div class="ngp-form" data-id="12345" data-databag="everybody"></div>
