Overview
The No Answer visibility condition lets you show a question only when another question has been left blank.
Accessing Visibility Logic
From the left navigation, click Forms
Click Form Templates
Click the name of a form template to open it in the Form Builder
Click the Edit button on the question you want to configure
Click the eye icon (Visible) in the rules panel on the right side of the question
The Visibility right pane opens
How to Set a "No Answer" Visibility Condition
Show a question only when a specific question elsewhere in the form has been left unanswered.
In the Form Builder, click the Edit button on the question you want to configure
Click the eye icon in the rules panel on the right side of the question
The Visibility right pane opens
From the Condition dropdown, select When
From the Question dropdown, select the question whose blank state should trigger this one (must be a Dropdown, Radio Button, Select Button, Text, or Textarea question)
Under Answered with, open the dropdown and select No answer (question is left unanswered/blank)
Click Done to save
The question you configured will now appear on the form only when the selected trigger question has been left blank.
How to Combine "No Answer" with AND / OR Logic
Use "No answer" as one condition within a more complex multi-condition visibility rule.
Open the Visibility right pane for the question you want to configure
Set the first condition using When and select the trigger question
Under Answered with, select No answer (question is left unanswered/blank)
To add AND logic, click Add filter within Group 1 and configure the second condition
To add OR logic, click Add Group and configure the alternative scenario
Click Done to save
Note: For more detail on AND/OR logic, see the AND/OR Visibility Logic on Form Questions guide.
Understanding the "No Answer" Option
The "No answer" option appears in the Answered with dropdown alongside the other available response conditions:
Any response — Question appears when the trigger question is answered with anything
Specific response(s) — Question appears when the trigger question matches one of the selected values
No answer (question is left unanswered/blank) — Question appears when the trigger question has not been answered
Selecting "No answer" does not show an additional option picker — it is a simple condition with no values to configure. The question becomes visible the moment the trigger question is empty, and hides again if the trigger question is answered.
Supported Question Types
The "No answer" condition can be applied when the trigger question is one of the following types:
Dropdown
Multiselect
Radio Button
Select Button
Text (Input)
Textarea
Note: Checkbox, Information, Photo, and Signature question types do not support the "No answer" condition.
Use Cases
Ask why a dropdown was left blank
A form has a dropdown asking a technician to select an equipment condition. If the technician skips it, a follow-up text question appears asking them to explain why no condition was recorded.
Prompt for an explanation when no option applies
A dropdown lists standard failure codes. If none of them apply and the technician leaves the field blank, a separate text field appears so they can describe the issue in their own words. This avoids forcing a technician to pick an inaccurate code just to move past the question.
Surface a "Not applicable" path without adding it as a dropdown option
Rather than cluttering a dropdown with an N/A option, a separate question asking for the reason can appear only when the dropdown is left unanswered — keeping the dropdown options clean while still capturing the missing context.
Best Practices
Use for Required Follow-Ups: If a question should only appear when a prior question was skipped — for example, asking why something was left blank — the "No answer" condition is the right choice over building a workaround with multiple specific conditions.
Test Both States: After configuring a "No answer" condition, preview the form and verify the question appears when the trigger is blank and disappears when the trigger is answered.
Combine with AND Logic When Needed: If a question should appear when a dropdown is blank AND another condition is also true, use "Add filter" to layer conditions rather than creating a separate question.
Keep the Trigger Question Visible: The "No answer" condition only fires when the trigger question is accessible to the user filling out the form. If the trigger question itself is hidden by other visibility rules, the "No answer" condition may not behave as expected.
Troubleshooting
Issue: The "No answer" option does not appear in the "Answered with" dropdown
Solution: The trigger question type must be Dropdown, Multiselect, Radio Button, Select Button, Text, or Textarea.
Verify the trigger question type is Dropdown, Multiselect, Radio Button, Select Button, Text, or Textarea
Checkbox, Information, Photo, and Signature questions do not support the "No answer" condition — select a different trigger question
Issue: The question is not appearing when the trigger is left blank
Solution: Confirm the condition is set to When or For with Answered with: No answer, and that the trigger question is visible on the form.
Confirm the condition is set to When and Answered with: No answer — not Always or Never
Preview the form and leave the trigger question completely blank (do not type and clear — confirm the field is empty)
Check that the trigger question itself is visible on the form — if the trigger is hidden, the condition cannot evaluate
Issue: The question appears even when the trigger question is answered
Solution: Confirm the condition is set to No answer and not Any response.
Open the Visibility right pane and confirm the condition is set to No answer, not Any response
Clear the logic and re-configure if needed
Summary
The "No answer" visibility condition shows a form question when a specified trigger question has been left blank. Select No answer (question is left unanswered/blank) from the Answered with dropdown when configuring a When condition in the Visibility right pane. This condition works on Dropdown, Multiselect, Radio Button, Select Button, Text, and Textarea question types, and can be combined with AND/OR logic for more complex rules.
