Is it better to use Checkboxes or Radio Buttons, when there are two or more fields and at least one of them must be filled out to pass validation?
My concern comes to the validation errors that will show after the user clicks save with each of the two control types at their default state.
The Checkbox validation would be: "At least one Identification Type is Required. Whereas the Radio Buttons validation would be "Social Security Number is Required".
Are there any best practices for situations where users can enter both options but only one must be entered to pass validation?
