Question details
Users need to enforce exactly one answer between "Yes" and "No" in a PDF form without making both fields mandatory.

- Device & OS
- not provided
- Scenario
- Creating or formatting a fillable PDF form with a mandatory, mutually exclusive question.
- Observed behavior
- When separate "Yes" and "No" checkboxes are marked as required, the form incorrectly prevents submission unless the user checks both boxes.
Ensure you are using a PDF editor with advanced form-creation capabilities, such as Adobe Acrobat or WPS Office PDF Editor, to adjust interactive field properties.
Use a Required Radio Button Group
By replacing checkboxes with a radio button group, you can naturally restrict selections to only one option while enforcing a required response.
Checkboxes act independently; if you make multiple checkboxes required, the system will demand that every single one is ticked. Radio buttons, on the other hand, are designed for 'either/or' questions. When grouped together and set as required, the form will only ask for one selection from the entire group to proceed.
Open your PDF form in edit mode, navigate to the form tools, and insert two radio buttons near your 'Yes' and 'No' labels.
Double-click the first radio button to open its Properties. Enter a specific Group Name (e.g., 'Question1_YesNo'). Do the exact same for the second radio button. Sharing a name ties them together so only one can be selected at a time.
In the Options tab of the Properties window, assign the 'Radio Button Choice' or export value of the first button to 'Yes', and the second button to 'No'.
While still in the Properties menu for either button, check the box labeled 'Required'. Because they are grouped, this setting applies to both, ensuring the user must click one of them before saving or submitting.
Create Interactive PDF Forms with WPS Office
WPS Office PDF Editor provides an intuitive interface for designing fillable forms, allowing you to seamlessly insert, group, and manage radio buttons to ensure accurate data collection.
- 1. Open PDF in WPS Office: Launch WPS Office and open your existing PDF document or create a new blank one.
- 2. Access the Form Tab: Navigate to the 'Form' tab on the top ribbon menu to access interactive field tools.
- 3. Insert Radio Buttons: Click the 'Radio Button' icon, then click on the page to place your 'Yes' and 'No' fields.
- 4. Group and Require: Right-click the fields to open Properties, give them the exact same name to link them, and tick the 'Required' option.
Frequently Asked Questions
Why do my users have to check both "Yes" and "No" when I set them as required?
If you are using checkboxes, making them required tells the software that each specific box must be ticked. To fix this, you must delete the checkboxes and replace them with a radio button group.
Can I set a default value for the radio buttons?
Yes. While in form editing mode, you can select one of the radio buttons (e.g., "No") to be the default state when the document is opened. This automatically satisfies the "Required" condition.
How do users clear a radio button selection if they click it by mistake?
Standard radio buttons cannot be completely deselected once clicked unless another option in the same group is chosen. If a "Neither" state is acceptable, you should include a third radio button labeled "N/A" or provide a "Reset Form" button.
Will these required radio buttons work on mobile PDF viewers?
Yes, standard PDF radio button groups are widely supported and will maintain their mutually exclusive and required behaviors on most modern mobile PDF viewer apps.
