How to Add Conditional Logic to Forms

Step-by-step guide

1

Build your form with all possible fields

Start by adding all the fields your form might need, including fields that will only be shown conditionally. For example, if you have a dropdown like 'How long have you been a member?', you might add a follow-up field that only appears for certain answers — this is the field you'll conditionally show.

2

Select a field and find its logic settings

Click the field you want to conditionally show or hide to open its editor panel. Scroll down to the 'Show this field when...' section at the bottom. This is where you'll define the conditions that control when this field appears to respondents.

3

Add a condition group

Click '+ Add condition group' to create a rule. Choose a source field from the dropdown, pick an operator (equals, not equals, contains, etc.), and enter a value. The field will only appear when the condition is met. You'll see a 'Conditional' badge on the field in the canvas to confirm logic is active. Add more conditions or groups for complex branching.

4

Test the logic

Preview the form and fill it out as a respondent would. Verify that conditional fields appear and disappear correctly based on your answers. Test edge cases — what happens when you change an answer back? Make sure required conditional fields don't block submission when they're hidden.

Tips

• Start simple — one condition per field. Add complexity only when needed
• Use conditional logic to keep forms short by hiding irrelevant follow-up questions
• Conditional required fields are only enforced when the field is visible
• Test your logic with different answer combinations to catch edge cases
• Combine conditional logic with multi-page forms for clean, progressive disclosure
