Radio buttons should be used within a sbb-radio-button-group.
Pressing a radio checks it and unchecks the previously selected radio, if any.
They can also be controlled programmatically by setting the value property of the parent radio group to the value of the radio.
Usage
Within a group of radio buttons, only one radio button can be selected at a time.
If you need to select more than one item, it is recommended to use checkboxes.
<!-- 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>
</sbb-radio-button-group>States
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>
<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-group>
<!-- 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>
<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-group>Deselecting Radios
In order to deselect a radio inside the group you can use the allowEmptySelection property on the parent radio group,
which enables the radios to be deselected (by default, a selected cannot be deselected).
Accessibility
In order to ensure readability for screen-readers, please provide an aria-label attribute for the sbb-radio-button-group.
