Forms and messages

Show form questions only when they're needed

Make a question appear, disappear or become required depending on what someone answered earlier on the form.

Rules let you keep a form short and still ask follow-up questions, but only of the people they apply to. A rule reads like a sentence: if someone picks this answer, then show that question.

It may be turned off for your site. Ask us and we'll take care of it.

Before you start

You need a form made with the Advanced Forms widget already on the page, with both the question that triggers the rule and the question it changes. See Build a form with several steps.

Steps

  1. Log in to your site editor and open the page with the form.
  2. Click the form to open its floating menu, then click Settings.
  3. Click the Logic tab, then + Add Rule.
  4. Name the rule so you'll remember it. Only you see the name.
  5. Under IF, choose the question to watch. Then choose how to compare it, and type the answer you're waiting for. To test for a match, use is equal to or is not equal to. To test for a blank answer, use is empty or is not empty. To test for particular words, use starts with, ends with, contains or does not contain.
  6. Under THEN, choose what should happen: show, hide, make optional or make required. Then choose which question it applies to.
  7. Click Save.
  8. Preview the page and try every answer to make sure the right questions appear.
  9. Publish. If you don't see a Publish button, tell us and we'll publish it for you.

Examples

  • A catering form asks "Type of event". If the answer is "Wedding", show "Number of guests" and "Venue".
  • A repair form asks "How urgent is it?". If the answer is "Today", make "Best phone number" required.
  • A quote form asks "Do you have photos?". If the answer is "Yes", show the file upload.

Watch out

  • Don't delete a question that a rule depends on. The form will misbehave, and the rule shows a Logic issue warning. Change or remove the rule first.
  • A question or step that has a rule can't be copied.
