Fields

Documentation

  • Required Field Groups

    Ask for one of several fields instead of all of them — tag two or more fields with the same group name and the form requires at least one of them (“email or phone”).

  • Email Verification (OTP)

    Require visitors to confirm a 6-digit code sent to their email address before the form can be submitted, so every entry carries a real, reachable mailbox.

  • Unique ID

    Stamp every submission with your own reference number — a prefix/suffix around a race-safe sequential counter or a random token, usable in emails, PDFs and webhooks.

  • Bank Account (IBAN / CZ / SK)

    Validate IBANs from any country and Czech/Slovak domestic bank account numbers offline by checksum, with a bank name hint — no external service, no API key.

  • Confirm field

    A confirmation field that validates if its value matches another field (useful for confirming emails, passwords, etc.).

  • Enhanced Email Field

    Block free email providers (like Gmail or Yahoo) together with disposable addresses or restrict specific domains to collect only valid business emails.

  • Checkbox or Radio with “Other” Option

    Let users choose from predefined options or add their own custom response. Supports both checkboxes (multiple choice) and radio buttons (single choice), with input types configurable as text or textarea.

  • EU VAT (Business number)

    Field for entering EU VAT numbers, with automatic validation through the VIES service.

  • IČO (Identification Number)

    Three new fields for Czech, Slovak, and combined Czech/Slovak IČO—complete with validation via ARES and FinStat on submission.
