Checkbox groups

How can I have a group of checkboxes - as in if you click on any other is unchecked. I saw a "group" for radio buttons.

I'd just create my own JavaScript function for this. I don't see that functionality built into the check boxes.

Thanks! I saw radio buttons had that function and thought maybe checkboxes could have the same thing. Is there a way to add that to checkboxes?

The standard is to use radiobuttons (round) for a single selection and checkboxes (square) for multiple selection. So we would not want to encourage checkboxes that work like radiobuttons as it could confuse people. Some alternatives to radiobuttons are a Selector() or Tabs().
