Notes

1). The radio button will be part of the form controller. so label, positions, validations should be handled in form controller.

2). When the Radio button is not part of form then we will be using independent components along with it. for example for the label, we can use the label component. and validations can be handled during CTA on a respective page based on business requirements.

3). In few cases, preselection might result in incorrect inputs. Ex: Gender selection in a form. In this case, we should offer no preselection and decide whether user input is mandatory or not depending on the use case.
