Basic Usage

Radio components are typically used individually as part of a radio group. Each radio represents a single option in a mutually exclusive set.

        name="basic-radio"
        value="option1"
        checked={selectedValue === 'option1'}
        onChange={(e) => setSelectedValue(e.target.value)}
      >
        Option 1
      </Radio>
      <Radio
        name="basic-radio"
        value="option2"
        checked={selectedValue === 'option2'}
        onChange={(e) => setSelectedValue(e.target.value)}
      >
        Option 2
      </Radio>
      <Radio
        name="basic-radio"
        value="option3"
        checked={selectedValue === 'option3'}
        onChange={(e) => setSelectedValue(e.target.value)}
      >
        Option 3
      </Radio>
    </VStack>
  );
}

Radio Groups

The recommended way to use Radio components is with a ControlGroup for better accessibility and easier state management.

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

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

  return (
    <ControlGroup
      role="radiogroup"
      ControlComponent={Radio}
      label="Choose a cryptocurrency"
      options={options}
      value={selectedCurrency}
      onChange={(e) => setSelectedCurrency(e.target.value)}
      name="currency-radio-group"
    />
  );
}

        checked={selectedColor === 'default'}
        onChange={(e) => setSelectedColor(e.target.value)}

      <Radio
        name="color-radio"
        value="green"
        checked={selectedColor === 'green'}
        onChange={(e) => setSelectedColor(e.target.value)}
        controlColor="accentBoldGreen"
      >
        Custom Green
      </Radio>
      <Radio
        name="color-radio"
        value="purple"
        checked={selectedColor === 'purple'}
        onChange={(e) => setSelectedColor(e.target.value)}
        controlColor="accentBoldPurple"
      >
        Custom Purple
      </Radio>
    </VStack>
  );
}

        checked={false}
        disabled
