You will have to coordinate with all UKHSA teams using this type of form if you're replacing this page controller completely or rewrite this as a non-breaking change. (Might be fine - just a warning!)

No teams are using this controller other than mine :)

assume just shortcutting types here for ease whilst you prototype?

Not all of these types will be needed, so some will be removed

RepeatingFieldPageController is just intended to repeat a single field multiple times (i.e. 1 page which has 1 field that repeats). Has this option been added to RepeatingFieldPageController to allow recursive repeating fields?

This solution utilises existing RepeatingFieldPageController functionality - see/test out the attached form to get an idea of how it all comes together

why is + 'Container' needed?

Why does the csrf cookie needed to be deleted? I would also just be careful about using delete in general, since it would mutate request.payload directly. It might be safe in this instance but can cause non-obvious side-effects with how js handles objects (by reference)
If you need the payload without the csrf cookie - do something like this
const { crumb, ...payload } = request;There was a problem hiding this comment.
Fixed so that the payload object is cloned before the crumb is removed

This is an incomplete solution for allowing repeating sections of data, not just repeating single fields. To test this, use the attached JSON form:
