Is there any way to edit the CSS of the"non-mapped required fields"

We have a hard break (br) in our template file for showing those fields. You can remove that, or modify the HTML in the /plugins/jfbcprofiles/jomsocial.php file. Around line 83, you'll see variable being set called $groupHtml. That line sets the field's name, has a br, then has JomSocial render the field. You can remove the br, wrap that in a span, or do whatever else may help you out.

Hope that helps,
Alex

No way to do template overrides for that. When I pointed you to that file, I actually added a note to our 'to-do' list to break that into a template-able file in the future. Never thought about it before, but could definitely help some people.

Thanks for the idea, but for now, you'll have to hack at that file. Keep note of your changes though, as you will need to re-implement them in the 4.1 release.
