Option Buttons Display Type
Option buttons are controls that display two or more mutually exclusive choices, such as male/female, or green/blue/yellow.
Guidelines for the use of option buttons are:
•If possible, make one button the default.
•Use option buttons in groups of two or more, otherwise use a check box.
•You should not specify too many values, because a separate button represents each value. If there are many options, consider using a dropdown list box.
