- Product
- PDF Editor
- Device & OS
- not provided
- Scenario
- Creating or editing an interactive PDF form where the same radio button selection needs to be reflected simultaneously on different pages or sections of the document.
- Observed behavior
- The goal is to ensure that when a form filler selects an option in one radio button group, all other corresponding instances update together.
Ensure your PDF editor supports interactive form creation and that you have noted the exact field names and export values you intend to use for your radio buttons.
Configure Radio Buttons to Update in Unison
Use identical field names and export values for radio buttons placed in different locations to synchronize their selections.
Interactive PDF forms rely on field names to manage data. When multiple form fields share the exact same name and export value, the PDF viewer treats them as a single data point. By configuring these properties correctly, you can display the same user selection on multiple pages without requiring the user to click it multiple times.
Open your PDF form in edit mode, insert a radio button from the form controls menu, and double-click it to open the Properties panel.
In the Properties panel, assign a specific 'Name' to the radio button field and navigate to the 'Options' tab to set the 'Radio Button Choice' (or export value).
Copy the original radio button and paste it into the other desired locations within the document, or manually create new ones ensuring you type in the exact same field Name and Choice value.
While still in the Properties Options tab for these duplicated buttons, check the box labeled 'Buttons with the same name and choice are selected in unison'.
Exit form editing mode and click through your radio button options to verify that all corresponding instances in the document update together automatically.

Use WPS Office to Create and Edit Interactive PDF Forms
WPS Office provides a comprehensive suite of PDF tools, allowing you to easily add, configure, and sync interactive form fields like radio buttons, checkboxes, and text fields.
- 1. Open the PDF Form: Launch WPS Office, open your PDF document, and navigate to the 'Form' tab on the top ribbon.
- 2. Insert Radio Buttons: Select the 'Radio Button' tool to place a new interactive button on your page.
- 3. Configure Properties: Double-click the newly created button to open its Properties menu. Set the Field Name and define the Export Value.
- 4. Sync Multiple Buttons: Copy and paste the button to other locations, ensuring they share the same properties and that the unison option is activated.

Frequently Asked Questions
Why are my duplicated radio buttons acting independently?
This usually happens if the duplicated radio buttons have slight variations in their field names or export values. Ensure both the name and choice values match exactly, and check that the 'selected in unison' setting is enabled in the field properties.
Can I sync checkboxes in the same way as radio buttons?
Yes, checkboxes can also be synchronized across a PDF form. By giving them the exact same field name and export value in their properties, checking one box will automatically check all matching boxes.
Will these synchronized buttons work if the PDF is opened in a web browser?
In most modern web browsers that support interactive PDF forms, the synchronized behavior will function correctly. However, for the best compatibility and reliable form-filling experience, users should open the PDF in a dedicated PDF reader like WPS Office.
