Choice Components

You now know how to collect text input from users, but there are many occasions for which you would rather give users a finite set of choices than have them enter the data in a text component. Using a set of buttons or a list of items tells your users what choices they have. (It also saves you the trouble of error checking.) In this section, you learn how to program checkboxes, radio buttons, lists of choices, and sliders.

Checkboxes

If you want to collect just a “yes” or “no” input, use a checkbox component. Checkboxes automatically come with labels that identify them. The user usually checks the box by clicking inside it and turns off the check mark by clicking inside the box again. To toggle the check mark, the user can also press the space bar when the focus is in the checkbox.
