Say if you want a custom field called 'User Details' and you want this field to contain 3 fields called:
Then you want the ability to add more sets of this bundle of three. Is that possible?
What is this type of field even called?
Thanks in advance
Thanks @John Funk as quick example here is how you can handle requests for multiple users or items in a form. It's not perfect as you can't add an infinite number such as in Table Grid, but using conditional logic and sections can allow for rich forms.

Jira has no way to do this natively, and hence you'll need apps to do something like it.
The closest I have have used is Idalko's Table Grid, but I would check the marketplace for others that may be better for you rather than go on one recommendation.
