Question details
The user needs to remove a red validation border that continues to display around required radio buttons in a PDF form even after a valid selection has been made.

- Device & OS
- not provided
- Scenario
- Filling out or designing interactive PDF forms that feature required fields and automatic validation indicators.
- Observed behavior
- The red validation border remains permanently visible on required radio buttons after a user completes the selection, instead of disappearing automatically upon successful form submission.
Verify that you are using a PDF editor with advanced form field capabilities (such as standard Adobe Acrobat or WPS Pro) and ensure that your document is completely free of strict protection passwords.
Verify Standard Form Submission Settings
Standard PDF functionality automatically handles required-field indicators. Successful form submission clears these visual errors.
In a correctly configured PDF form, required fields acquire a red border only after a form submission fails due to an incomplete required field. The border should be automatically removed upon a successful submission without requiring extra scripts.
Ensure that all required fields within the PDF form accurately reflect a completed status and that radio button groups have a definitively selected value.
Click the Submit button on the PDF form. Monitor the form actions to confirm the successful submission. Upon success, the PDF reader will naturally clear the red validation border.
Switch to your PDF form editing mode. Right-click the affected radio button, select 'Properties', and verify under the 'General' tab that the field accurately reflects the 'Required' checkbox state without conflicting validation rules.
Inspect and Remove Custom Form Scripts
Custom JavaScript or custom appearance settings might be forcing the red border to remain visible regardless of the submission status.

Frequently Asked Questions
Why does my PDF form show a red border around fields?
The red border is a default indicator in many standard PDF viewers highlighting that a field is marked as 'Required' but has not been filled out yet, or that it failed to pass form validation during a submission attempt.
Can I disable required field highlighting in PDF viewers?
Yes, most modern PDF readers feature a preferences section commonly located under 'Forms' where you can turn off options like 'Show border hover color for fields' or 'Highlight existing fields', though doing so only alters your local view, not the actual file design.
Does WPS Office support editing interactive PDF radio buttons?
Yes, WPS Office Pro includes comprehensive PDF form editing tools that seamlessly allow you to insert, modify, and adjust the exact properties and validation status of radio buttons, text fields, and dropdowns.
