#### GroupBox

The GroupBox offers an easy way to combine [<span style="color: rgb(230, 126, 35);">RadioButtons </span>](https://doc316en.candera.eu/link/1156#bkmrk-radiobutton)to a RadioButtonGroup. The special functionality of this Control is to select just one selection object ([<span style="color: rgb(230, 126, 35);">RadioButton</span>](https://doc316en.candera.eu/link/1156#bkmrk-radiobutton)) at the same time. So if one of the objects get selected, the others automatically get deselected.

Furthermore it is possible to set a node as default selected object.

<p class="callout info">There can also be a Layouter attached as child of the GroupBox to order the RadioButtons.</p>

The visual appearance can be configured with a background image (9Patch Image) which can be resized by using the Layout.
