Radiogroup
A group of radio buttons. Only one radio button inside the group can be selected at a time. The radio buttons may either direct children of the radiogroup or descendants. Place the radiogroup inside a groupbox if you would like a border or caption around the group. The radiogroup defaults to vertical orientation.
To set the radio button that will be selected by default, set the selected attribute of a child radio element.

disabled
Type: boolean
Indicates whether the radiogroup is disabled or not. If this attribute is set to true, the radiogroup is disabled. This is usually drawn with the text in grey. If the radiogroup is disabled, it does not respond to user actions. The element cannot be focused and the command event will not fire. The element will still respond to mouse events. To enable the radiogroup, leave the attribute out entirely as opposed to setting the value to false.
focused
Type: boolean
This attribute is set to true if the radiogroup element is focused.
preference Mozilla 1.8
Type: element id
Connects the radiogroup to a corresponding preference. This attribute only has any effect when used inside a prefwindow. The value of the preference will be updated to match the value property of the radiogroup.
tabindex
Type: integer
The tab order of the element. The tab order is the order in which the focus is moved when the user presses the Tab key. Elements with a higher tabindex are later in the tab order sequence.
