Chips

Chips represent complex entities in small blocks, such as a contact.

• Module @rmwc/chip
• Import styles:
  • Using CSS Loader
    • import '@rmwc/chip/styles';
  • Or include stylesheets
    • '@material/chips/dist/mdc.chips.css'
    • '@rmwc/icon/icon.css'

<ChipSet>
  <Chip selected label="Cookies" />
  <Chip label="Pizza" />
  <Chip label="Icecream" />
</ChipSet>

<ChipSet>
  <Chip icon="favorite" label="Cookies" trailingIcon="close" />
</ChipSet>

function Example() {
  const [selected, setSelected] = React.useState(false);
  return (
    <ChipSet>
      <Chip
        key="my-chip"
        label="Click Me"
        checkmark
        selected={selected}
        onRemove={(evt) => console.log('onRemove', evt.detail)}
        onInteraction={(evt) => {
          console.log('onInteraction', evt.detail);
          setSelected(!selected);
        }}
        onTrailingIconInteraction={(evt) =>
          console.log('onTrailingIconIteraction', evt.detail)
        }
        trailingIcon="close"
      />
    </ChipSet>
  );
}

Filter and Choice Chipsets

You can specify a ChipSet as either a filter of choice which slightly changes the visual styling of selected chips. While material-components-web has some built in functionality for chip sets, it doesn't fit well with React's unidirectional data flow. It is recommended you use standard React patterns to store selected chips in your state and render them accordingly.

Clicking on the trailing close icon will trigger a close animation and put the chip in an exited state, but it is up to you to remove component out from rendering. The you use the onRemove prop implement this behavior.

function Example() {
  const [selected, setSelected] = React.useState({
    cookies: false,
    pizza: false,
    icecream: false
  });
  const toggleSelected = (key) =>
    setSelected({
      ...selected,
      [key]: !selected[key]
    });

  return (
    <ChipSet filter>
      <Chip
        selected={selected.cookies}
        checkmark
        onInteraction={() => toggleSelected('cookies')}
        label="Cookies"
      />
      <Chip
        selected={selected.pizza}
        checkmark
        onInteraction={() => toggleSelected('pizza')}
        icon="local_pizza"
        label="Pizza"
      />
      <Chip
        selected={selected.icecream}
        checkmark
        onInteraction={() => toggleSelected('icecream')}
        icon="favorite_border"
        label="Icecream"
      />
    </ChipSet>
  );
}

function Example() {
  const [selected, setSelected] = React.useState({
    cookies: false,
    pizza: false,
    icecream: false
  });
  const toggleSelected = (key) =>
    setSelected({
      ...selected,
      [key]: !selected[key]
    });

  return (
    <ChipSet choice>
      <Chip
        selected={selected.cookies}
        onInteraction={() => toggleSelected('cookies')}
        label="Cookies"
      />
      <Chip
        selected={selected.pizza}
        onInteraction={() => toggleSelected('pizza')}
        icon="local_pizza"
        label="Pizza"
      />
      <Chip
        selected={selected.icecream}
        onInteraction={() => toggleSelected('icecream')}
        icon="favorite_border"
        label="Icecream"
      />
    </ChipSet>
  );
}

Chip

A Chip component.

Props

Name	Type	Description
checkmark	boolean	Includes an optional checkmark for the chips selected state.
children	ReactNode	Additional children will be rendered in the text area.
foundationRef	Ref<any>	Advanced: A reference to the MDCFoundation.
icon	IconPropT	Instance of an Icon Component.
id	string	An optional chip ID that will be included in callback evt.detail. If this is not passed, RMWC will attempt to use the "key" prop if present.
label	ReactNode	Text for your Chip.
onInteraction	(evt: ChipOnInteractionEventT) => void	A callback for click or enter key. This should be used over onClick for accessibility reasons. evt.detail = { chipId: string }
onRemove	(evt: ChipOnRemoveEventT) => void	A callback that is fired once the chip is in an exited state from removing it. evt.detail = { chipId: string }
onTrailingIconInteraction	(evt: ChipOnTrailingIconInteractionEventT) => void	A callback for click or enter key for the trailing icon. material-components-web always treats this as an intent to remove the chip. evt.detail = { chipId: string }
