Chapter 8. Form Handling > Working with Radio Buttons

Working with Radio Buttons

Radio buttons are an either/or interface element that let the user pick one (and only one) choice within a group of options. Radio buttons should be used when one of those options is required.

In this case, you can only pick one of these choices, and you must make a choice.
