Question details
The user needs to synchronize radio buttons across different locations in a PDF form so that selecting an option in one area automatically selects the exact same option in another area.

- Device & OS
- not provided
- Scenario
- Designing an interactive PDF form where duplicate responses are required, such as a 'Yes' selection in the main body syncing to display the same 'Yes' selection in the document header.
- Observed behavior
- The goal state is achieved by configuring the form fields so that the radio buttons share the exact same selected state across multiple locations within the document.
Ensure you are using a PDF editor that supports interactive form creation and that your document is currently in Form Editing mode so you can access field properties.
Sync Radio Buttons by Matching Field Names and Export Values
The standard method to link two or more radio buttons in a PDF form is to assign them the exact same field name and export value.
In PDF forms, fields that share the identical Field Name act as a single data entity. By giving radio buttons in different physical locations the exact same Field Name and Export Value, you force the PDF viewer to synchronize their states. When a user clicks one, all others with matching properties update instantly.
Launch your PDF editor and open your document. Navigate to the Form or Prepare Form toolset to activate editing capabilities.
Add a radio button to the primary location on your page. Right-click or double-click the newly placed button to open its Properties dialog.
In the General tab of the Properties dialog, enter a specific Field Name (for example, 'ConsentStatus').
Navigate to the Options tab. Set the Export Value to match the choice (for example, 'Yes'). Close the Properties dialog.
Insert a second radio button in the secondary location, such as the document header, and open its Properties dialog.
Enter the exact same Field Name ('ConsentStatus') in the General tab, and the exact same Export Value ('Yes') in the Options tab. Save your document and test the form to see the selections sync.

Frequently Asked Questions
Why are my PDF radio buttons allowing multiple selections instead of linking?
If radio buttons allow multiple selections, they likely have different Field Names. To group them so only one can be chosen—or to link identical options across pages—they must share the exact same Field Name in their properties.
Can I link checkboxes in the same way as radio buttons?
Yes, checkboxes can also be synchronized. By assigning multiple checkboxes the exact same Field Name and Export Value, checking one will automatically check all others sharing those identical properties.
Does linking radio buttons work on mobile PDF viewers?
Yes, as long as the mobile PDF viewer supports interactive forms (such as the WPS Office mobile app), the linked radio buttons will function correctly. This behavior is embedded into the PDF file's standard form properties.
