Using chips

Chips are compact elements that allow users to enter information, select a choice, filter content, or trigger an action. Chips must always be used inside a chip set.

Installing chips

npm install @material/chips

Styles

@use "@material/chips/styles";

JavaScript instantiation

Note: there's work planned to replace the mdc-evolution-* prefix of chips with the standard mdc-chip-* prefix.

import {MDCChipSet} from '@material/chips';
const chipset = new MDCChipSet(document.querySelector('.mdc-evolution-chip-set'));

Chips

Chips are comprised of chip sets which are comprised of chip instances which are in turn comprised of actions. See the readme for each subcomponent for more detail.

Basic action chip set example

<span class="mdc-evolution-chip-set" role="grid">
  <span class="mdc-evolution-chip-set__chips" role="presentation">
    <span class="mdc-evolution-chip" role="row" id="c0">
      <span class="mdc-evolution-chip__cell mdc-evolution-chip__cell--primary" role="gridcell">
        <button class="mdc-evolution-chip__action mdc-evolution-chip__action--primary" type="button" tabindex="0">
          <span class="mdc-evolution-chip__ripple mdc-evolution-chip__ripple--primary"></span>
          <span class="mdc-evolution-chip__text-label">Chip one</span>
        </button>
      </span>
    </span>
    <span class="mdc-evolution-chip" role="row" id="c1">
      <span class="mdc-evolution-chip__cell mdc-evolution-chip__cell--primary" role="gridcell">
        <button class="mdc-evolution-chip__action mdc-evolution-chip__action--primary" type="button" tabindex="-1">
          <span class="mdc-evolution-chip__ripple mdc-evolution-chip__ripple--primary"></span>
          <span class="mdc-evolution-chip__text-label">Chip two</span>
        </button>
      </span>
    </span>
  </span>
</span>
