BuddyPress.org

If you create a field group called Business Details, you simply add as many fields you want!
Let’s say, you want that users can fill about 5 companies or society. In this case, you need to create a field for each input, in other words 5 fields. And if you need more details for each, you add the fields you need, one by one:

Business 1: [___]

Address 1: [___]

Office 1 hours: [___]

Business 2: [___]

Address 2: [___]

Office 2 hours: [___]

Or if you use a lot of details, you group each businness separately.

For better clarity of the default profile details output, when you have a lot of information to display, is to use this very handy plugin: buddypress-profile-tabs

I looked into this a while ago. I don’t know if any plugins have provided it — if so, the code will be hacky — because achieving this requires changing some data storage we do in BuddyPress, which is a bit of a complicated issue to resolve well.
