An example of doing this with a checkbox field is shown below and the same method applies for radio fields too.
- Edit the Checkbox field by clicking the settings icon.
- Click the Checkboxes tab.
- Optionally click the expand icon at the top to make the label setting easier to edit.
- In the label of the checkbox, enter the HTML for adding a link.
- Click Save & Close
