A group of radiobuttons will be created with the `<tc:selectOneRadio/>` tag. Static entries are added with `<tc:selectItem/>` tag. A list from a controller is added with `<tc:selectItems value="\#{controller.list}"/>`.

Tag Library Documentation: | |

Radiobutton group with a label. The last item is disabled. Also the label set on top with the `labelLayout` attribute.

    <tc:selectOneRadio label="Radio Group" labelLayout="top"/>

To display the radio buttons horizontally use the `inline="true"` attribute.

Add number1 to number2 or subtract number2 from number1.

The radiobuttons are hardcoded with `<tc:selectItem itemLabel="1" itemValue="1"/>`. The buttons trigger an action in the controller: `<tc:button label="Addition" action="\#{selectOneRadioController.add}"/>`

Select a planet on the left. One the right side, you can select one of the moons.

The planets are added with `<f:selectItems value="\#{selectOneRadioController.planets}"/>`. The radiogroup of the planets also contain a `<f:ajax render="moonradio">` element, which allows to rerender the radiogroup with the ID 'moonradio' every time, the value changed in the planet-radiogroup.
