How to Configure Radio Buttons for an Adobe Sign Signer
Question details
The user needs to configure a radio-button field so that a signer can edit it, but the field is currently locked to Signature and Prefill roles in Adobe Acrobat Sign.

- Product
- Adobe Acrobat Sign
- Device & OS
- not provided
- Scenario
- Setting up an interactive PDF form in Adobe Acrobat Sign where the recipient needs to select options using radio buttons.
- Observed behavior
- The radio-button field is locked to Signature and Prefill roles, preventing it from being configured as a standard signer-editable field.
Ensure you have the original PDF document and sufficient authoring permissions to edit form fields and modify roles before proceeding.
Recreate the Radio Button as a Standard Form Field
Since the field was likely mapped incorrectly as a signature field initially, recreating it using the Prepare Form tool is the most effective way to assign it properly to the Signer role.
In Adobe Acrobat Sign, field type and role settings often become permanently locked once a field has been mapped or designated as a signature field. Because of this restriction, you cannot simply change a locked field's role directly from Signature/Prefill to Signer.
Open the original document in Adobe Acrobat and navigate to the 'Prepare Form' tool from the right-hand pane or the Tools menu.
Locate the existing radio-button group that is locked to the Signature or Prefill roles, select it, and press the Delete key.
Select the Radio Button icon from the form authoring toolbar, place it on the document, and configure the choices as standard form fields.
Upload the updated document to the Adobe Sign authoring interface, select the newly created radio-button group, and assign its role to 'Signer' so the recipient can interact with it.

Frequently Asked Questions
Why is my PDF form field locked to the Prefill role?
This usually happens when the field is mistakenly mapped as a signature or specialized data field during the initial creation. Deleting the field and recreating it as a standard form field will resolve this issue.
Can I convert an existing signature field into a radio button?
No, Adobe Sign restricts converting specialized signature fields into standard form fields like radio buttons once they are mapped. You must delete the restricted field and create a new radio button group.
Are PDF forms created in WPS Office compatible with Adobe Acrobat?
Yes, interactive PDF forms containing text fields, checkboxes, and radio buttons created in WPS Office are fully standard-compliant and perfectly compatible with Adobe Acrobat and Adobe Reader.
