Show an initial first set of a repeating group when it is required

Omschrijving / Description

When having a repeating group as required, at least one instance needs to be filled in. As it is now, a user still has to invoke the fields by clicking the "+" button. This seems unnecessary to me. Showing an initial set of fields in this case would fix this story #2344 as well; since the required-asterisk wouldn't be needed at all at the repeating-group level; the asterisks at the fields (now showing immediately on tab load) would suffice.

Added value / Toegevoegde waarde

Make the initial appearance of fields match the intention set in the form.

Reading the documentation, it seems like a similar feature was planned/implemented before? https://open-forms.readthedocs.io/en/2.0.0_a/manual/forms/examples/repeating_groups.html

However, I don't see this mentioned option in the properties window of 2.0.0:

Yes, but we ran into formio bugs and decided to scrap that option :(

See #2081 for context, adding blocked label as this is blocked by formio/formio.js#4620

@SilviaAmAm our documentation needs updating, see comment from Erik

Is it possible to re-add this feature, as the formio bug is closed?

[sergei-maertens]

The upstream issue was closed because it was outdated, not because it was fixed. Additionally even if it was fixed, it's a mountain of work to upgrade to newer Formio versions since we had to patch a lot of things ourselves. Even upgrading to their latest 4.13.x patch release breaks Open Forms :(
