The sbb-radio-button-group is a component which can be used as a wrapper for
a collection of either sbb-radio-buttons, sbb-radio-button-panels,
or sbb-selection-expansion-panels.

<!-- The first option will be selected by default -->
<sbb-radio-button-group value="Value one" aria-label="Radio group label">
  <sbb-radio-button value="Value one">Option one</sbb-radio-button>
  <sbb-radio-button value="Value two">Option two</sbb-radio-button>
  <sbb-radio-button value="Value three">Option three</sbb-radio-button>

Pressing a sbb-radio-button checks it and unchecks the previously selected one, if any.
They can also be controlled programmatically by setting the value property of the parent radio group to the value of the radio.

Please note that within a sbb-radio-button-group, only one sbb-radio-button can be selected at a time;
if you need to select more than one item, it is recommended to use the sbb-checkbox-group component.


The radio group can have different states:

  • can be completely disabled by setting the property disabled;
  • can be required by setting the property required.
<!-- All child radio buttons will be disabled -->
<sbb-radio-button-group value="Value one" aria-label="Radio group label" disabled>

<!-- The radio group and all child radio buttons will be marked as required -->
<sbb-radio-button-group value="Value one" aria-label="Radio group label" required>

In order to deselect a sbb-radio-button inside the sbb-radio-button-group,
you can use the allowEmptySelection property, which will be proxied to the inner sbb-radio-button
enabling their deselection (by default, a selected sbb-radio-button cannot be deselected).

<sbb-radio-button-group allow-empty-selection> ... </sbb-radio-button-group>


The orientation property is used to set item orientation. Possible values are horizontal (default) and vertical.
The optional property horizontalFrom can be used in combination with orientation='vertical' to
indicate the minimum breakpoint from which the orientation changes to horizontal.

<sbb-radio-button-group orientation="vertical" horizontal-from="large">


Consumers can listen to the native change/input event on the sbb-radio-button-group component
to intercept the selection's change; the current value can be read from event.detail.value.


In order to ensure readability for screen-readers, please provide an aria-label attribute for the sbb-radio-button-group.
