CheckBox controls are small square boxes used to set independent options. When they are selected, they display a mark (typically, either an X or a check mark). When they are not selected, they are empty.
Since check boxes are independent of each other, you can group them without affecting their behavior. Grouping check boxes makes the window easier for the user to understand and use.
Typically, check boxes have two states: on and off. You can also use a third state, unknown or unspecified. In the third state, the check is grayed.
