Check boxes are a widget to enable one or more options in a group.

[edit] Guidelines

• Use checkboxes for non-exclusive options. Mutually exclusive options should use a set of radio buttons.
• For more than 10 options, use a list.
• Checking a checkbox should always "enable" an option or change the state of an option to "on". Checking a negative or disabling option is a double negative and causes confusion and errors.
• Checkbox labels are in sentence style capitalization
