Radio button

<RadioButton> controls are used to create a group of buttons. The user can only select one radio button from this group at a time.

Attribute	Description
`displayName`	Label of the radio button Translatable Data binding possible Possible values: Any string
`optionValue`	Required. Technical value that is processed. Data binding (string or boolean) possible Possible values: Any string Note; It is possible to select additional radio buttons by clicking on a radio button. To do this, the `optionValue` attribute must be identical for all radio buttons you want to select by selecting one of them.
`value`	Required. Radio buttons with the same `value` form a group from which only one radio button can be selected at a time. Data binding (string or boolean) required Possible values: Any string Note: By default, radio buttons are not selected when the web app is opened. The values for `optionValue` and `value` must be identical so that a radio button is already selected when the web app opened.
`background`	Defines a color for the background of the control. This setting overwrites the default color of the color scheme! This attribute doesn't work with the `Maps` and `HtmlDocument` controls! Possible values: Hexadecimal color value, e.g. `ff5a00` Do not use a hash in front of the color value! do not use a shortened notation of the color value!

		</Properties>
		<FlowLayout>
			<RadioButton optionValue="true" value="#group" displayName="Button 1" />
			<RadioButton optionValue="false" value="#group" displayName="Button 2"/>
		</FlowLayout>
</DetailComponent>
