ChoiceGroup / React

Organizes checkboxes or radio buttons into a single related group.

To implement ChoiceGroup component into your project you’ll need to add the import:

import ChoiceGroup from "@kiwicom/orbit-components/lib/ChoiceGroup";
import Radio from "@kiwicom/orbit-components/lib/Radio";

After adding import into your project you can use it simply like:

<ChoiceGroup label="What was the reason for your cancellation?">
  <Radio label="Reason one" value="one" />
  <Radio label="Reason two" value="two" />
  <Radio label="Reason three" value="three" />
</ChoiceGroup>

Props

Table below contains all types of the props available in the ChoiceGroup component.

Name Type Default Description
dataTest string Optional prop for testing purposes.
children React.Node (args) => React.Node The content of the ChoiceGroup, normally Radio or Checkbox. Pass a function for advanced usage, see “Render prop” in Storybook for an example.
error Translation The error to display beneath the ChoiceGroup. Also, the Checkboxes/Radios will turn red when you pass some value.
label Translation Heading text of the ChoiceGroup
labelAs enum "h4" The element used to render the label into.
labelSize enum "normal" The size type of Heading.
onChange event => void | Promise Function for handling onChange event. See Functional specs
filter boolean false Changes visual appearance of child components, to contain background on hover and updates padding.
onOnlySelection (event, {value: string, label: string}) => void | Promise<any> Function for handling onOnlySelection, read more in Functional specs.
onlySelectionText Translation Property for passing translation string when you want to use the onOnlySelection callback.

enum

labelElement labelSize
"h2" "normal"
"h3" "large"
"h4"
"h5"
"h6"

Passing a function as children

If you need more control over how to render ChoiceGroup, for example using react-window, you can pass a function to children instead of React.Node, which receives an object containing the following properties:

  • Container is the inner container where Radio/Checkbox elements are placed
  • Item is the component that should wrap Radio/Checkbox elements
  • spacing is the spacing between items, which you need to apply yourself

This is a barebones example:

<ChoiceGroup onChange={ev => doSomething(ev)}>
  {({ Container, Item, spacing }) => (
    <Container style={{ display: 'flex', flexDirection: 'column', gap: spacing }}>
      <Item>
        <Radio label="Reason one" value="two">
      </Item>
      <Item>
        <Radio label="Reason two" value="two">
      </Item>
      <Item>
        <Radio label="Reason three" value="three">
      </Item>
    </Container>
  )}
</ChoiceGroup>

For more realistic usage you can check out the “Render prop” example in Storybook.

Functional specs

  • onChange props in <Radio /> or <Checkbox /> will be overrode by internal onChange function
  • If you want to handle selecting field, pass onChange to <ChoiceGroup /> and it will be always triggered when <Radio /> or <Checkbox /> should change
  • onChange will return SyntheticEvent of field that should change
<ChoiceGroup onChange={ev => doSomething(ev)}>
  <Radio label="Reason one" value="one" />
  <Radio label="Reason two" value="two" />
  <Radio label="Reason three" value="three" />
</ChoiceGroup>
  • onOnlySelection can be used only when filter prop is used.
  • filter pattern with onOnlySelection is used where multiple checkboxes in different states are presented to the user, and the user wants to choose only one of them.
  • filter pattern with onOnlySelection shouldn’t contain radio buttons.
