Radio Button Group
A radio button group is an optional user interface element that prompts the user to choose only one of a predefined list of options. Along with the combo box and list, you use the radio button group to make a choice that drives the task flow.
The following image shows an example radio button group that displays a predefined list of options. You can choose one of these options.

The input that a radio button receives determines the next task step that appears, or the data that appears in the next task view. For example, clicking the Credit Card Dispute radio button option will open the CC Dispute view for example. Clicking the Balance Inquiry radio button option will open a different view, and so on.
The multiple radio buttons that a radio button group contains constitute a single control item. For more information, see the following topics:
