Drawers
The MDC Navigation Drawer is used to organize access to destinations and other functionality on an app.
Design & API Documentation
Installation
npm install @material/drawer
HTML Structure
<aside class="mdc-drawer">

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

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.

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-current="page">

<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
Dismissible Drawer Full Height Drawer
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-current="page">
<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>

</header>
<main class="main-content" id="main-content">
<div class="mdc-top-app-bar--fixed-adjust">
App Content
</div>
</main>
</div>
</body>
Dismissible Drawer Below Top App Bar
In cases where the drawer appears below the top app bar you will want to follow the markup shown below. The mdc-drawer__content
and main-content
elements will also scroll independently of each other. The mdc-top-app-bar
, mdc-drawer
and mdc-drawer-app-content
will be sibling to each other. The mdc-top-app-bar--fixed-adjust
helper class will be applied to mdc-drawer
and mdc-drawer-app-content
elements to adjust the position with top app bar.
<body>
<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>
<aside class="mdc-drawer mdc-drawer--dismissible mdc-top-app-bar--fixed-adjust">
<div class="mdc-drawer__content">
<div class="mdc-list">
<a class="mdc-list-item mdc-list-item--activated" href="#" aria-current="page">
<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 mdc-top-app-bar--fixed-adjust">
<main class="main-content" id="main-content">
App Content
</main>
</div>
</body>
The CSS to match either case looks like this:
body {
display: flex;
height: 100vh;
}
.mdc-drawer-app-content {
flex: auto;
overflow: auto;
position: relative;
}
.main-content {
overflow: auto;
height: 100%;
}
.app-bar {
position: absolute;
}
.mdc-top-app-bar {
z-index: 7;
}
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 Drawer
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-current="page">
<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();
});
Modal Drawer
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();
});
