Forms
How do I add conditional logic?
Show, hide, require fields, or jump to a page based on how someone answers.
Conditional logic makes a form react to answers — you can reveal follow-up questions, hide irrelevant ones, make a field required, or send the respondent to a different page.
Add a rule
- In the builder, open the Logic tab on the right.
- Add a rule built from a WHEN condition and a THEN action.
- Choose how conditions combine: Match all of (every condition must be true) or Match any of (any one is enough).
- Build each condition from a field, an operator, and a value.
- Choose the action to run when the rule matches.
- Save the form.
Operators
Conditions can use these operators:
- equals / not equal
- contains
- greater than / less than
- is empty / is filled
- is one of
Actions
When a rule matches, it can:
- Show field — reveal a hidden field.
- Hide field — hide a field.
- Require field — make a field mandatory.
- Jump to page — send the respondent to another page.
Example
Add a Single choice question "Are you an existing customer?" Then create a rule: WHEN that field equals "Yes" THEN Show field for the customer account number.
Use Preview to test your logic by filling the form as a respondent would, before you publish or re-publish it.
