Radio button

Radio button component examples

import {LegacyStack, RadioButton} from '@shopify/polaris';
import {useState, useCallback} from 'react';

function RadioButtonExample() {
  const [value, setValue] = useState('disabled');

  const handleChange = useCallback(
    (_: boolean, newValue: string) => setValue(newValue),
    [],
  );

  return (
    <LegacyStack vertical>
      <RadioButton
        label="Accounts are disabled"
        helpText="Customers will only be able to check out as guests."
        checked={value === 'disabled'}
        id="disabled"
        name="accounts"
        onChange={handleChange}
      />
      <RadioButton
        label="Accounts are optional"
        helpText="Customers will be able to check out with a customer account or as a guest."
        id="optional"
        name="accounts"
        checked={value === 'optional'}
        onChange={handleChange}
      />
    </LegacyStack>
  );
}

Best practices

Radio buttons should:

• Always be used with an associated label component.
• Be part of a list of radio buttons that:
  • Include at least two or more choices.
  • Are used to have merchants select only one option.
  • Include mutually exclusive options—this means that each option must be independent from every other option in the list. For example: Red, blue, and yellow are mutually exclusive. Red, blue, yellow, red/blue are not mutually exclusive.
  • List options in a rational order that makes logical sense.
  • Have a default option selected whenever possible.

Content guidelines

Radio button labels

Radio button labels should:

• Be introduced with a colon or a heading
• Start with a capital letter

• Not end in punctuation if it’s a single sentence, word, or a fragment

Toggle (Android and iOS only)

Toggle labels should:

• Be clear what merchants are enabling or disabling
• Start with a capital letter

Toggle values should:

• Never be labeled

Related components

• To make simple lists of radio buttons easier to build, use the choice list component
• For long lists of options, consider the select component to avoid overwhelming merchants
• To present merchants with a list of checkboxes, use the choice list component with the “allow multiple” option
• To display non-interactive list of related content, use the content list component

Accessibility

Screen readers convey the state of the radio button automatically.

• Use the disabled prop to apply the HTML disabled attribute to the radio button <input>. This prevents merchants from being able to interact with the radio button, and conveys its inactive state to assistive technologies.
• Use the id prop to provide a unique id attribute value for the radio button. If an id isn’t provided, then the component generates one. All radio buttons must have unique id values to work correctly with assistive technologies.

Labeling

• The required label prop conveys the purpose of the radio button to all merchants
• Use the labelHidden prop to visually hide the label but make it available to assistive technologies
• When you provide help text via the helpText prop or an inline error message via the error prop, the help or error content is conveyed to screen reader users with the aria-describedby attribute

Keyboard support

• Move focus to the radio button group using the tab key (or shift + tab when tabbing backwards)
• Use the up and down arrow keys to change which radio button is selected
