## Common questions

<AccordionGroup>
  <Accordion title="Does the URL field validate the format?">
    The form validates that the entered value is a properly formatted URL (begins with http\:// or https\://). If the format is invalid, an error message is shown.
  </Accordion>

  <Accordion title="Can I use reject duplicates on a URL field?">
    Yes. Enable **Reject duplicate values** to ensure each URL is only submitted once. Useful for preventing the same website from being submitted multiple times.
  </Accordion>

  <Accordion title="Can I pre-fill a URL based on another field?">
    Yes. The default value supports `@` variable references, so you can construct a URL dynamically from other form field values.
