Current Text Box List fields only let the admin predefine a fixed number of rows. On the live form, the respondent can't add their own extra lines.

Request: optional toggle to allow Text Box List to support "Add another" / "+" buttons on the front-end so respondents can add/remove rows as needed.

Use cases:

Literally any type of list where a wide number of options could be submitted.

This keeps data structured (one item per row), which is much cleaner for organization, analytics, automations, and workflows, all without forcing admins to guess how many rows to create or wasting vertical space with empty boxes.
