HTML Structure

<aside class="mdc-drawer">
  <div class="mdc-drawer__content">
    <nav class="mdc-list">
      <a class="mdc-list-item mdc-list-item--activated" href="#" aria-selected="true">
        <i class="material-icons mdc-list-item__graphic" aria-hidden="true">inbox</i>
        <span class="mdc-list-item__text">Inbox</span>
      </a>
      <a class="mdc-list-item" href="#">
        <i class="material-icons mdc-list-item__graphic" aria-hidden="true">send</i>
        <span class="mdc-list-item__text">Outgoing</span>
      </a>
      <a class="mdc-list-item" href="#">
        <i class="material-icons mdc-list-item__graphic" aria-hidden="true">drafts</i>
        <span class="mdc-list-item__text">Drafts</span>
      </a>
    </nav>
  </div>
</aside>

Icons

We recommend using Material Icons from Google Fonts:

<head>
  <link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
</head>

However, you can also use SVG, Font Awesome, or any other icon library you wish.

Styles

@import "@material/drawer/mdc-drawer";
@import "@material/list/mdc-list";

JavaScript Instantiation

For permanently visible drawer, the list must be instantiated for appropriate keyboard interaction:

import {MDCList} from "@material/list";
const list = MDCList.attachTo(document.querySelector('.mdc-list'));
list.wrapFocus = true;

Other variants use the MDCDrawer component, which will instantiate MDCList automatically:

import {MDCDrawer} from "@material/drawer";
const drawer = MDCDrawer.attachTo(document.querySelector('.mdc-drawer'));

Variants

Drawer with separate list groups

<aside class="mdc-drawer">
  <div class="mdc-drawer__content">
    <nav class="mdc-list">
      <a class="mdc-list-item mdc-list-item--activated" href="#" aria-selected="true">
        <i class="material-icons mdc-list-item__graphic" aria-hidden="true">inbox</i>
        <span class="mdc-list-item__text">Inbox</span>
      </a>
      <a class="mdc-list-item" href="#">
        <i class="material-icons mdc-list-item__graphic" aria-hidden="true">star</i>
        <span class="mdc-list-item__text">Star</span>
      </a>
      <a class="mdc-list-item" href="#">
        <i class="material-icons mdc-list-item__graphic" aria-hidden="true">send</i>
        <span class="mdc-list-item__text">Sent Mail</span>
      </a>
      <a class="mdc-list-item" href="#">
        <i class="material-icons mdc-list-item__graphic" aria-hidden="true">drafts</i>
        <span class="mdc-list-item__text">Drafts</span>
      </a>

      <hr class="mdc-list-divider">
      <h6 class="mdc-list-group__subheader">Labels</h6>
      <a class="mdc-list-item" href="#">
        <i class="material-icons mdc-list-item__graphic" aria-hidden="true">bookmark</i>

        <span class="mdc-list-item__text">Work</span>
      </a>
    </nav>
  </div>
</aside>

Drawer with Header

Drawers can contain a header element which will not scroll with the rest of the drawer content. Things like account switchers and titles should live in the header element.

<aside class="mdc-drawer">
  <div class="mdc-drawer__header">
    <h3 class="mdc-drawer__title">Mail</h3>
    <h6 class="mdc-drawer__subtitle">email@material.io</h6>
  </div>
  <div class="mdc-drawer__content">
    <nav class="mdc-list">
      <a class="mdc-list-item mdc-list-item--activated" href="#" aria-selected="true">
        <i class="material-icons mdc-list-item__graphic" aria-hidden="true">inbox</i>
        <span class="mdc-list-item__text">Inbox</span>
      </a>
      <a class="mdc-list-item" href="#">
        <i class="material-icons mdc-list-item__graphic" aria-hidden="true">send</i>
        <span class="mdc-list-item__text">Outgoing</span>
      </a>
      <a class="mdc-list-item" href="#">
        <i class="material-icons mdc-list-item__graphic" aria-hidden="true">drafts</i>
        <span class="mdc-list-item__text">Drafts</span>
      </a>
    </nav>
  </div>
</aside>

Dismissible Drawer

Dismissible drawers are by default hidden off screen, and can slide into view. Dismissible drawers should be used when navigation is not common, and the main app content is prioritized.

<body>
  <aside class="mdc-drawer mdc-drawer--dismissible">
    <div class="mdc-drawer__content">
      <nav class="mdc-list">
        <a class="mdc-list-item mdc-list-item--activated" href="#" aria-selected="true">
          <i class="material-icons mdc-list-item__graphic" aria-hidden="true">inbox</i>
          <span class="mdc-list-item__text">Inbox</span>
        </a>
        <a class="mdc-list-item" href="#">
          <i class="material-icons mdc-list-item__graphic" aria-hidden="true">send</i>
          <span class="mdc-list-item__text">Outgoing</span>
        </a>
        <a class="mdc-list-item" href="#">
          <i class="material-icons mdc-list-item__graphic" aria-hidden="true">drafts</i>
          <span class="mdc-list-item__text">Drafts</span>
        </a>
      </nav>
    </div>
  </aside>

  <div class="mdc-drawer-app-content">
    App Content
  </div>
</body>

Apply the mdc-drawer-app-content class to the sibling element after the drawer for the open/close animations to work.

Usage with Top App Bar

In cases where the drawer occupies the full viewport height, some styles must be applied to get the dismissible drawer and the content below the top app bar to independently scroll and work in all browsers.

In the following example, the mdc-drawer__content and main-content elements should scroll independently of each other. The mdc-drawer--dismissible and mdc-drawer-app-content elements should then sit side-by-side. The markup looks something like this:

<body>
  <aside class="mdc-drawer mdc-drawer--dismissible">
    <div class="mdc-drawer__content">
      <div class="mdc-list">
        <a class="mdc-list-item mdc-list-item--activated" href="#" aria-selected="true">
          <i class="material-icons mdc-list-item__graphic" aria-hidden="true">inbox</i>
          <span class="mdc-list-item__text">Inbox</span>
        </a>
        <a class="mdc-list-item" href="#">
          <i class="material-icons mdc-list-item__graphic" aria-hidden="true">send</i>
          <span class="mdc-list-item__text">Outgoing</span>
        </a>
        <a class="mdc-list-item" href="#">
          <i class="material-icons mdc-list-item__graphic" aria-hidden="true">drafts</i>
          <span class="mdc-list-item__text">Drafts</span>
        </a>
      </div>
    </div>
  </aside>

  <div class="mdc-drawer-app-content">
    <header class="mdc-top-app-bar app-bar" id="app-bar">
      <div class="mdc-top-app-bar__row">
        <section class="mdc-top-app-bar__section mdc-top-app-bar__section--align-start">
          <a href="#" class="demo-menu material-icons mdc-top-app-bar__navigation-icon">menu</a>
          <span class="mdc-top-app-bar__title">Dismissible Drawer</span>
        </section>
      </div>
    </header>

    <main class="main-content" id="main-content">
      <div class="mdc-top-app-bar--fixed-adjust">
        App Content
      </div>
    </main>
  </div>
</body>

The CSS to match it looks like this:

// Note: these styles do not account for any paddings/margins that you may need.

body {
  display: flex;
  height: 100vh;
}

.mdc-drawer-app-content {
  flex: auto;
  overflow: auto;
}

.main-content {
  overflow: auto;
  height: 100%;
}

.app-bar {
  position: absolute;
}

The JavaScript to toggle the drawer when the navigation button is clicked looks like this:

import {MDCTopAppBar} from "@material/top-app-bar";
const topAppBar = MDCTopAppBar.attachTo(document.getElementById('app-bar'));
topAppBar.setScrollTarget(document.getElementById('main-content'));
topAppBar.listen('MDCTopAppBar:nav', () => {
  drawer.open = !drawer.open;
});

Modal drawers are elevated above most of the app’s UI and don’t affect the screen’s layout grid.

<body>
  <aside class="mdc-drawer mdc-drawer--modal">
    <div class="mdc-drawer__content">
      <nav class="mdc-list">
        <a class="mdc-list-item mdc-list-item--activated" href="#" aria-selected="true">
          <i class="material-icons mdc-list-item__graphic" aria-hidden="true">inbox</i>
          <span class="mdc-list-item__text">Inbox</span>
        </a>
        <a class="mdc-list-item" href="#">
          <i class="material-icons mdc-list-item__graphic" aria-hidden="true">send</i>
          <span class="mdc-list-item__text">Outgoing</span>
        </a>
        <a class="mdc-list-item" href="#">
          <i class="material-icons mdc-list-item__graphic" aria-hidden="true">drafts</i>
          <span class="mdc-list-item__text">Drafts</span>
        </a>
      </nav>
    </div>
  </aside>

  <div class="mdc-drawer-scrim"></div>
  <div>Main Content</div>
</body>

The mdc-drawer-scrim next sibling element is required, to protect the app’s UI from interactions while the modal drawer is open.

Accessibility

Focus Management

It is recommended to shift focus to the first focusable element in the main content when drawer is closed or one of the destination items is activated. (By default, MDC Drawer restores focus to the menu button which opened it.)

Dismissible Drawer

Restore focus to the first focusable element when a list item is activated or after the drawer closes. Do not close the drawer upon item activation, since it should be up to the user when to show/hide the dismissible drawer.

const listEl = document.querySelector('.mdc-drawer .mdc-list');
const mainContentEl = document.querySelector('.main-content');

listEl.addEventListener('click', (event) => {
  mainContentEl.querySelector('input, button').focus();
});

document.body.addEventListener('MDCDrawer:closed', () => {
  mainContentEl.querySelector('input, button').focus();
});

Close the drawer when an item is activated in order to dismiss the modal as soon as the user performs an action. Only restore focus to the first focusable element in the main content after the drawer is closed, since it’s being closed automatically.

const listEl = document.querySelector('.mdc-drawer .mdc-list');
const mainContentEl = document.querySelector('.main-content');

listEl.addEventListener('click', (event) => {
  drawer.open = false;
});

document.body.addEventListener('MDCDrawer:closed', () => {
  mainContentEl.querySelector('input, button').focus();
});
