Selectable

Checkboxes and Radios can be included as part of ListItemMeta. It is recommended when using these that you are using controlled components, and that you put your interaction handler on the ListItem itself. Notice the readOnly prop is also set on the individual form elements.

function Example() {
  const [selectedIndex, setSelectedIndex] = React.useState(-1);

  return (
    <List
      selectedIndex={selectedIndex}
      onAction={(evt) => setSelectedIndex(evt.detail.index)}
    >
      <ListItem>Cookies</ListItem>
      <ListItem>Pizza</ListItem>
      <ListItem>Cake</ListItem>
    </List>
  );
}

function Example() {
  const shoppingList = ['Cookies', 'Pizza', 'Icecream'];
  const [selectedIndex, setSelectedIndex] = React.useState<number[]>(
    []
  );

  const handleSelect = (evt) => {
    setSelectedIndex((indices) =>
      indices.includes(evt.detail.index)
        ? indices.filter((_) => _ !== evt.detail.index)
        : [...indices, evt.detail.index]
    );
  };

  return (
    <List
      aria-label="Shopping List"
      selectedIndex={selectedIndex}
      onAction={handleSelect}
    >
      {shoppingList.map((key) => (
        <ListItem key={key}>
          {key}
          <ListItemMeta>
            <Checkbox readOnly label={key} />
          </ListItemMeta>
        </ListItem>
      ))}
    </List>
  );
}

function Example() {
  const [checked, setChecked] = React.useState(
    new Map<string, boolean>([
      ['Cookies', false],
      ['Pizza', false],
      ['Icecream', false]
    ])
  );

  return (
    <List>
      {['Cookies', 'Pizza', 'Icecream'].map((key) => (
        <ListItem
          key={key}
          onClick={() =>
            setChecked((prev) => new Map(prev).set(key, !prev.get(key)))
          }
        >
          {key}&amp;nbsp;
          <ListItemMeta>
            <Switch label={key} checked={checked.get(key)} />
          </ListItemMeta>
        </ListItem>
      ))}
    </List>
  );
}

function Example() {
  const mealchoices = ['Beef', 'Chicken', 'Vegetable Lasagna'];
  const [selectedIndex, setSelectedIndex] = React.useState(0);

  const handleSelect = (evt) => setSelectedIndex(evt.detail.index);

  return (
    <List
      aria-label="Please Pick a Meal"
      selectedIndex={selectedIndex}
      onAction={handleSelect}
    >
      {mealchoices.map((key) => (
        <ListItem key={key}>
          {key}
          <ListItemMeta>
            <Radio readOnly name="meal-choices-group" label={key} />
          </ListItemMeta>
        </ListItem>
      ))}
    </List>
  );
}
