CheckboxGroup

Name

Description

The CheckboxGroup class provides the means to group multiple Checkbox items into a mutual exclusion set, so that only one checkbox in the set has the value true at any time. The checkbox with the value true is the currently selected checkbox. Mutually exclusive checkboxes usually have a different appearance from regular checkboxes and are also called "radio buttons."
