v2.2 implementation allows only "Tab", Multiple Custom Data.
This will be handled subsequent to re-architecting of custom data as outlined here:
Multiple instance boolean flag will be stored at the custom data GROUP level (i.e. a custom data group is configured to either allow or not allow multiple values).
Need to iron out how multi-value fields displayed on view and edit screens
- For Display, show the most recent "n" values with a link to "Show All"?
- For Edit, provide fields to update any of the most recent "n" values plus a field to insert a new value? OR ...
For Import (and other non-UI operations) - if we're updating an existing record with multi-value custom field data - is it ok to always "insert new value"?
