Conditional logic
Conditional logic keeps forms short by showing each respondent only the questions that apply to them.
How rules work
A rule targets one field and decides whether it is visible. Each rule contains one or more conditions, and you choose whether ALL conditions must match or ANY single condition is enough.
Conditions compare a previous field's answer using operators such as is, is not, contains, does not contain, is empty, is not empty, greater than and less than.
Creating a rule
Rules live in the Logic tab of the builder.
- 1Open the Logic tab.
- 2Choose the field you want to show or hide.
- 3Add one or more conditions referencing earlier fields.
- 4Pick ALL or ANY matching, then save and test in the preview.
Good practice
Reference only fields that appear before the target field, so the answer exists when the rule is evaluated. Hidden fields are not required and their values are not submitted, so a hidden required field will never block a submission.
Frequently asked questions
Does logic work on quizzes too?
Yes, the same rule engine is available for interactive quiz and form flows.
Do hidden fields still get submitted?
No. If a field is hidden by a rule at submission time, no value is stored for it.
Can one field depend on several answers?
Yes. Add multiple conditions to one rule and choose ALL or ANY matching.
