About a radio button

A radio button is used out of two or more items to choose only only one item. It is necessary to give the same group name altogether to the item which serves as the candidate of selection at this time. Since it will operate independently mutually if group names differ, two or more selections will be able to be performed. A check box will be used supposing it allows two or more selections.
