Is this a radio button group? For example, how old are you


o 10 - 19


o 20 - 29


o 30 - 39


o 40+





In this example, I would have a button group, because the user cannot select more than one option.





When buttons are in groups, the individual state of each button is unnecessary to know. Calling the value of the radio button group will just return the value of the button selected.
