>It's really just a property of a list of checkboxes, how many you can select, not an entirely different class of UI component. Not really at all. Radio buttons are part of a group so 3 radio buttons are related and exclusive, there 3 check-boxes represent 3 different unrelated things. The typical example is selecting your gender/sex , you use a radio btn group and put 2 radio buttons or if you are less competent dev you recreate this with checkboxes, scripting and extra validation.
