Required fields & validation

Good data starts at the form. A few simple settings make sure attendees give you what you need, in the right shape.

Required vs. optional

Every field has a required toggle. Required fields must be filled in before an attendee can submit — optional ones can be left blank. Use required sparingly so the form stays quick to complete.

Built-in rules per field

Some fields offer extra checks:

• Number — set a minimum and maximum, so answers stay in a sensible range.
• Text area — set the number of rows to hint at how much you expect.
• Date — choose whether to also collect a time.
• File upload — limit the number of files and the accepted file kinds (images, PDFs, or other).

What attendees see

If something's missing or out of range, the form points it out at submission so the attendee can fix it before continuing — you only ever receive complete, valid responses.
