Deprecation Notice

󰎦

Deprecated Component

RadioGroup is deprecated and will be removed in a future version.

Use ControlGroup with role="radiogroup" instead for better accessibility, consistency, and maintainability.

󰔂

Types

RadioGroup onChange fails without a string type declaration for setGroup fns.

const [group, setGroup] = useState<string>();

Migration Guide

✅ Recommended: Using ControlGroup

The new recommended approach provides better accessibility, cleaner API, and consistent behavior across the design system.

Live Code

function RecommendedRadioGroup() {
  const options = [
    { value: 'btc', children: 'Bitcoin' },
    { value: 'eth', children: 'Ethereum' },
    { value: 'ltc', children: 'Litecoin' },
  ];

  const [selectedCurrency, setSelectedCurrency] = useState('btc');

  return (
    <VStack gap={2}>
      <ControlGroup
        role="radiogroup"
        ControlComponent={Radio}
        label="Choose a Currency"
        options={options}
        value={selectedCurrency}
        onChange={(e) => setSelectedCurrency(e.target.value)}
        name="recommended-radio-group"
      />
      <Text font="caption" color="fgMuted">
        Selected: {selectedCurrency}
      </Text>
    </VStack>
  );
}

Migration Steps

1. Replace RadioGroup with ControlGroup:

   // Old (deprecated)
   <RadioGroup
     value={selectedValue}
     onChange={onChange}
     options={{ btc: 'Bitcoin', eth: 'Ethereum' }}
   />
   
   // New (recommended)
   <ControlGroup
     role="radiogroup"
     ControlComponent={Radio}
     options={[
       { value: 'btc', children: 'Bitcoin' },
       { value: 'eth', children: 'Ethereum' }
     ]}
     value={selectedValue}
     onChange={onChange}
   />

2. Update options format:

   // Old: Object format
   const options = { btc: 'Bitcoin', eth: 'Ethereum' };
   
   // New: Array format
   const options = [
     { value: 'btc', children: 'Bitcoin' },
     { value: 'eth', children: 'Ethereum' },
   ];

3. Update onChange handler:

   // Old: Direct value callback
   const oldOnChange = (value) => setSelected(value);
   
   // New: Event-based handler
   const newOnChange = (e) => setSelected(e.target.value);

4. Add proper role:

   // Always include role="radiogroup" for accessibility
   <ControlGroup
     role="radiogroup"
     ControlComponent={Radio}
     // ... other props
   />

Legacy Usage (Deprecated)

󰣸

Legacy Example

The following examples show the deprecated RadioGroup usage. Do not use this in new code. Use ControlGroup instead.

Basic RadioGroup (Legacy)

Live Code

function LegacyRadioGroupDemo() {
  // static values should live outside the component in product code.
  const options = {
    btc: 'Bitcoin',
    eth: 'Ethereum',
    dai: 'Dai',
  };

  const [group, setGroup] = useState('btc');

  return (
    <VStack gap={2}>
      <Text font="headline">Currency Selection (Legacy RadioGroup)</Text>
      <RadioGroup
        aria-labelledby="choose-a-currency"
        id="currency-radio-group"
        label={
          <Text as="span" font="headline" id="choose-a-currency">
            Choose a currency
          </Text>
        }
        name="radio-group1"
        value={group}
        onChange={setGroup}
        options={options}
      />
      <Text font="caption" color="fgMuted">
        Selected: {group}
      </Text>
    </VStack>
  );
}

With Custom Label (Legacy)

Live Code

function LegacyRadioGroupWithLabel() {
  const options = {
    'yellow-jacket': 'Yellow Jacket',
    bruin: 'Bruin',
    bronco: 'Bronco',
  };

  const [mascot, setMascot] = useState('bruin');

  return (
    <RadioGroup
      aria-labelledby="choose-a-mascot"
      id="mascot-radio-group"
      label={
        <Text as="span" font="headline" id="choose-a-mascot">
          Choose a mascot
        </Text>
      }
      name="radio-group2"
      value={mascot}
      onChange={setMascot}
      options={options}
    />
  );
}

Color Customization (Legacy)

Like other control components (i.e. Checkbox, Switch), you can customize the color of the Radio by setting the controlColor prop.

Live Code

function CustomColors() {
  // static values should live outside the component in product code.
  const options = {
    btc: 'Bitcoin',
    eth: 'Ethereum',
    dai: 'Dai',
  };

  const [checked, setChecked] = useState(false);
  const [group, setGroup] = useState();

  return (
    <VStack>
      <Radio
        controlColor="accentBoldGreen"
        onChange={() => setChecked((s) => !s)}
        checked={checked}
      >
        Custom control color
      </Radio>
      <Divider paddingY={2} />
      <RadioGroup
        id="mascot-radio-group"
        aria-labelledby="choose-a-mascot"
        name="radio-group2"
        controlColor="accentBoldGreen"
        value={group}
        onChange={setGroup}
        options={options}
      />
    </VStack>
  );
}

For more advanced color customization, you can use additional style props on individual Radio components like background, borderColor, and color:

Live Code

function AdvancedCustomColors() {
  const [checked, setChecked] = useState(false);

  return (
    <VStack gap={2}>
      <Radio checked={checked} controlColor="bgPositive" onChange={() => setChecked((s) => !s)}>
        Control color prop
      </Radio>
      <Radio
        background={checked ? 'accentBoldPurple' : 'bg'}
        borderColor={checked ? 'bgNegative' : 'bgWarning'}
        checked={checked}
        color="bgPrimary"
        controlColor="bgPositive"
        onChange={() => setChecked((s) => !s)}
      >
        Advanced styling
      </Radio>
    </VStack>
  );
}
