Another way to explain what I’m looking for could be data collects.
Scenario: A user opens the page containing the form with 5 rows. He has a list of 10 people attending the event so he needs to add an additional 5 rows so he can input all 10 users.
I would like for him to be able to click a button on the page to add a new row.
I have looked at various form builders, gravity forms and table builders but doesn’t seem as any of them has the option to allow a user to add an additional row (or column) via the front page.
