With this plugin, you can greate groups of custom fields, like this:
[klikprint] type = fieldset_open multipleButton = true multiple = true [klikprint_download] type = file label = Kies een bestand om te uploaden relation=true class=file [klikprint_omschrijving] type = text size = 100 label = Omschrijf je download relation=true [klikprint] type = fieldset_close
The field relationships are messed up once you delete a field in one of the (duplicated) groups. When I look at the DB, there is also no discernible link between (in my case) the fields klikprint_omschrijving & klikprint_download, which sort of explains this behaviour. I'm thinking it just pulls all meta fields out of the database, and links them based on the order in which they appear in the query results. Which is asking for trouble.
