Notes

Checkboxes are one of several selection controls. A Checkbox takes binary user input, giving the user only two options. Notable props for Checkboxes include alignEnd, which changes the alignment of the label and the Checkbox, indeterminate, which fills the Checkbox with a value that is neither true nor false, and hideLabel, which causes the label not be displayed, although it will still be available to screen readers, as well as other props that alter the initial state (checked, disabled, etc.) of the Checkbox.

Usage

Since many selection inputs exist, Checkbox should be used only when a true/false or yes/no answer is requested of a user. Radio and Switch offer other alternatives for taking user input when more options are available. Examples and demos of this functionality are included under the corresponding Storybook tabs.
