Making Choices with Radio Buttons and Check Boxes,Buttons let the user choose a single command. However, many times, you may need to present the user with several options. You could display multiple buttons, where each button represents a single option, but this could look cluttered and messy. A more compact solution is to use radio buttons and check boxes.
