Create a table where the users can select previously created groups

[Febakke]

Description

App developer would like to produce a table that lists groups created by the users earlier in the form process. The users should be able to select each row in the table in relation to a new question.

Could be solved with a checkboxlist.

• Needs a way for the user to add new elements to the list

Considerations

• Should the user be able to create new groups when in this state?

Relevant info for those wanting this functionality:

• You can reference another (repeating) group in a Panel, in case the user might need to add a row to the group when they are working somewhere else in the app. This is related and reminded me about this need, but that functionality is not made to reach the same goal as this.
• You should be able to use existing repeating groups as options inside a dropdown/checkbox/radio list. This lets you implement this functionality, albeit with a different user interface.
• When New component: List #578 is implemented, you could perhaps use that component along with the above trick to use repeating groups as options to get almost the same UI, but without the option to add/edit data.

Apart from the options above, this issue describes a separate need in #107, so it should still be implemented at some point (unless the mentioned choices cover all current and future needs).

Additional development tasks:

• It should be possible to configure this as using a checkbox OR as a radio
• If using checkboxes, it should be possible to select/unselect all at once
• The data model bindings for this needs to somehow both identify what data (from the repeating group row) should be put into which field in the data model (assumed to be outside the repeating group).
• It should optionally be possibly to use this in an alternate manner; where a single boolean field inside the group is set (something akin to 'selected').

I was reminded about this issue, and so I'll comment again with later developments. There might be a way to use expressions (in the future) to create the data structure needed for the List component to do this. See relevant issues:

• Expressions: Support options from expression result #1180
• List component: remaining issues #925
