@material/drawer

What is @material/drawer?

@material/drawer is a Material Design implementation of a drawer component, which is used to create navigational sidebars in web applications. It provides a consistent and customizable way to implement drawers that can be either permanent, dismissible, or modal.

What are @material/drawer's main functionalities?

Permanent Drawer

A permanent drawer is always visible and typically used for navigation in desktop applications. The code sample shows how to initialize a permanent drawer using the @material/drawer package.

import { MDCPermanentDrawer } from '@material/drawer';

const drawer = MDCPermanentDrawer.attachTo(document.querySelector('.mdc-drawer--permanent'));

Dismissible Drawer

A dismissible drawer can be toggled open or closed by the user. This type of drawer is typically used in responsive web applications. The code sample demonstrates how to initialize and toggle a dismissible drawer.

import { MDCDismissibleDrawer } from '@material/drawer';

const drawer = MDCDismissibleDrawer.attachTo(document.querySelector('.mdc-drawer--dismissible'));
const drawerOpenButton = document.querySelector('.drawer-open-button');
drawerOpenButton.addEventListener('click', () => drawer.open = !drawer.open);

Modal Drawer

A modal drawer overlays the content and is typically used for mobile applications. The code sample shows how to initialize and open a modal drawer using the @material/drawer package.

import { MDCModalDrawer } from '@material/drawer';

const drawer = MDCModalDrawer.attachTo(document.querySelector('.mdc-drawer--modal'));
const drawerOpenButton = document.querySelector('.drawer-open-button');
drawerOpenButton.addEventListener('click', () => drawer.open = true);

Other packages similar to @material/drawer

react-sidebar

react-sidebar is a library for creating sidebars in React applications. It provides a flexible and customizable way to implement sidebars, but it does not follow Material Design guidelines as strictly as @material/drawer.

react-burger-menu

react-burger-menu is another React library for creating off-canvas menus. It offers a variety of animations and styles for the sidebar, making it more versatile in terms of design compared to @material/drawer.

rc-drawer

rc-drawer is a drawer component for React that supports both left and right side drawers. It is highly customizable and can be used in various types of web applications, but it does not provide the same level of built-in Material Design styling as @material/drawer.

README

MDC Drawer

The MDC Drawer component is a spec-aligned drawer component adhering to the Material Design navigation drawer pattern. It implements permanent, persistent, and temporary drawers. Permanent drawers are CSS-only and require no JavaScript, whereas persistent and temporary drawers require JavaScript to function, in order to respond to user interaction.

Installation

npm install --save @material/drawer

Permanent drawer usage

A permanent drawer is always open, sitting to the side of the content. It is appropriate for any display size larger than mobile.

TODO(sgomes): Give advice on how to hide permanent drawer in mobile.

<nav class="mdc-permanent-drawer mdc-typography">
  <div class="mdc-permanent-drawer__toolbar-spacer"></div>
  <div class="mdc-permanent-drawer__content">
    <nav id="icon-with-text-demo" class="mdc-list">
      <a class="mdc-list-item mdc-permanent-drawer--selected" href="#">
        <i class="material-icons mdc-list-item__start-detail" aria-hidden="true">inbox</i>Inbox
      </a>
      <a class="mdc-list-item" href="#">
        <i class="material-icons mdc-list-item__start-detail" aria-hidden="true">star</i>Star
      </a>
    </nav>
  </div>
</nav>
<div>
  Toolbar and page content go inside here.
</div>

In the example above, we've set the drawer above the toolbar, and are using a toolbar spacer to ensure that it is presented correctly, with the correct amount of space to match the toolbar height. Note that you can place content inside the toolbar spacer.

Permanent drawers can also be set below the toolbar:

<div>Toolbar goes here</div>

<div class="content">
  <nav class="mdc-permanent-drawer mdc-typography">
    <nav id="icon-with-text-demo" class="mdc-list">
      <a class="mdc-list-item mdc-permanent-drawer--selected" href="#">
        <i class="material-icons mdc-list-item__start-detail" aria-hidden="true">inbox</i>Inbox
      </a>
      <a class="mdc-list-item" href="#">
        <i class="material-icons mdc-list-item__start-detail" aria-hidden="true">star</i>Star
      </a>
    </nav>
  <main>
    Page content goes here.
  </main>
</div>

CSS classes:

Class	Description
mdc-permanent-drawer	Mandatory. Needs to be set on the root element of the component.
mdc-permanent-drawer__content	Mandatory. Needs to be set on the container node for the drawer content.
mdc-permanent-drawer__toolbar-spacer	Optional. Add to node to provide the matching amount of space for toolbar.

Persistent drawer usage

Persistent drawers can be toggled open or closed. The drawer sits on the same surface elevation as the content. It is closed by default. When the drawer is outside of the page grid and opens, the drawer forces other content to change size and adapt to the smaller viewport. Persistent drawers stay open until closed by the user.

Persistent drawers are acceptable for all sizes larger than mobile.

Class	Description
mdc-persistent-drawer	Mandatory. Needs to be set on the root element of the component.
mdc-persistent-drawer__drawer	Mandatory. Needs to be set on the container node for the drawer content.

Using the JS Component

MDC Persistent Drawer ships with a Component / Foundation combo which allows for frameworks to richly integrate the correct drawer behaviors into idiomatic components.

Including in code

ES2015

import {MDCPersistentDrawer, MDCPersistentDrawerFoundation, util} from 'mdc-drawer';

CommonJS

const mdcDrawer = require('mdc-drawer');
const MDCPersistentDrawer = mdcDrawer.MDCPersistentDrawer;
const MDCPersistentDrawerFoundation = mdcDrawer.MDCPersistentDrawerFoundation;
const util = mdcDrawer.util;

AMD

require(['path/to/mdc-drawer'], mdcDrawer => {
  const MDCPersistentDrawer = mdcDrawer.MDCPersistentDrawer;
  const MDCPersistentDrawerFoundation = mdcDrawer.MDCPersistentDrawerFoundation;
  const util = mdcDrawer.util;
});

Global

const MDCPersistentDrawer = mdc.drawer.MDCPersistentDrawer;
const MDCPersistentDrawerFoundation = mdc.drawer.MDCPersistentDrawerFoundation;
const util = mdc.drawer.util;

Automatic Instantiation

If you do not care about retaining the component instance for the persistent drawer, simply call attachTo() and pass it a DOM element.

mdc.drawer.MDCPersistentDrawer.attachTo(document.querySelector('.mdc-persistent-drawer'));

Manual Instantiation

Persistent drawers can easily be initialized using their default constructors as well, similar to attachTo.

import {MDCPersistentDrawer} from 'mdc-drawer';

const drawer = new MDCPersistentDrawer(document.querySelector('.mdc-persistent-drawer'));

Handling events

When the drawer is opened or closed, the component will emit a MDCPersistentDrawer:open or MDCPersistentDrawer:close custom event with no data attached. Events get emitted only when the drawer toggles its opened state, i.e. multiple consecutive drawer.open = true calls will result in only one MDCPersistentDrawer:open.

Using the Foundation Class

MDC Persistent Drawer ships with an MDCPersistentDrawerFoundation class that external frameworks and libraries can use to integrate the component. As with all foundation classes, an adapter object must be provided. The adapter for persistent drawers must provide the following functions, with correct signatures:

Method Signature	Description
addClass(className: string) => void	Adds a class to the root element.
removeClass(className: string) => void	Removes a class from the root element.
hasClass(className: string) => boolean	Returns boolean indicating whether element has a given class.
hasNecessaryDom() => boolean	Returns boolean indicating whether the necessary DOM is present (namely, the mdc-persistent-drawer__drawer drawer container).
registerInteractionHandler(evt: string, handler: EventListener) => void	Adds an event listener to the root element, for the specified event name.
deregisterInteractionHandler(evt: string, handler: EventListener) => void	Removes an event listener from the root element, for the specified event name.
registerDrawerInteractionHandler(evt: string, handler: EventListener) => void	Adds an event listener to the drawer container sub-element, for the specified event name.
deregisterDrawerInteractionHandler(evt: string, handler: EventListener) => void	Removes an event listener from drawer container sub-element, for the specified event name.
registerTransitionEndHandler(handler: EventListener) => void	Registers an event handler to be called when a transitionend event is triggered on the drawer container sub-element element.
deregisterTransitionEndHandler(handler: EventListener) => void	Deregisters an event handler from a transitionend event listener. This will only be called with handlers that have previously been passed to registerTransitionEndHandler calls.
registerDocumentKeydownHandler(handler: EventListener) => void	Registers an event handler on the document object for a keydown event.
deregisterDocumentKeydownHandler(handler: EventListener) => void	Deregisters an event handler on the document object for a keydown event.
getDrawerWidth() => number	Returns the current drawer width, in pixels.
setTranslateX(value: number) => void	Sets the current position for the drawer, in pixels from the border.
getFocusableElements() => NodeList	Returns the node list of focusable elements inside the drawer.
saveElementTabState(el: Element) => void	Saves the current tab index for the element in a data property.
restoreElementTabState(el: Element) => void	Restores the saved tab index (if any) for an element.
makeElementUntabbable(el: Element) => void	Makes an element untabbable.
notifyOpen() => void	Dispatches an event notifying listeners that the drawer has been opened.
notifyClose() => void	Dispatches an event notifying listeners that the drawer has been closed.
isRtl() => boolean	Returns boolean indicating whether the current environment is RTL.
isDrawer(el: Element) => boolean	Returns boolean indicating whether the provided element is the drawer container sub-element.

Temporary drawer usage

A temporary drawer is usually closed, sliding out at a higher elevation than the content when opened. It is appropriate for any display size.

<aside class="mdc-temporary-drawer mdc-typography">
  <nav class="mdc-temporary-drawer__drawer">
    <header class="mdc-temporary-drawer__header">
      <div class="mdc-temporary-drawer__header-content">
        Header here
      </div>
    </header>
    <nav id="icon-with-text-demo" class="mdc-temporary-drawer__content mdc-list">
      <a class="mdc-list-item mdc-temporary-drawer--selected" href="#">
        <i class="material-icons mdc-list-item__start-detail" aria-hidden="true">inbox</i>Inbox
      </a>
      <a class="mdc-list-item" href="#">
        <i class="material-icons mdc-list-item__start-detail" aria-hidden="true">star</i>Star
      </a>
    </nav>
  </nav>
</aside>

let drawer = new mdc.drawer.MDCTemporaryDrawer(document.querySelector('.mdc-temporary-drawer'));
document.querySelector('.menu').addEventListener('click', () => drawer.open = true);

Headers and toolbar spacers

Temporary drawers can use toolbar spacers, headers, or neither.

A toolbar spacer adds to the drawer the same amount of space that the toolbar takes up in your application. This is very useful for visual alignment and consistency. Note that you can place content inside the toolbar spacer.

<aside class="mdc-temporary-drawer mdc-typography">
  <nav class="mdc-temporary-drawer__drawer">

    <div class="mdc-temporary-drawer__toolbar-spacer"></div>

    <nav id="icon-with-text-demo" class="mdc-temporary-drawer__content mdc-list">
      <a class="mdc-list-item mdc-temporary-drawer--selected" href="#">
        <i class="material-icons mdc-list-item__start-detail" aria-hidden="true">inbox</i>Inbox
      </a>
      <a class="mdc-list-item" href="#">
        <i class="material-icons mdc-list-item__start-detail" aria-hidden="true">star</i>Star
      </a>
    </nav>
  </nav>
</aside>

A header, on the other hand, is a large rectangular area that maintains a 16:9 ratio. It's often used for user account selection. It uses an outer mdc-temporary-drawer__header for positioning, with an inner mdc-temporary-drawer__header-content for placing the actual content, which will be bottom-aligned.

<aside class="mdc-temporary-drawer mdc-typography">
  <nav class="mdc-temporary-drawer__drawer">

    <header class="mdc-temporary-drawer__header">
      <div class="mdc-temporary-drawer__header-content">
        Header content goes here
      </div>
    </header>

    <nav id="icon-with-text-demo" class="mdc-temporary-drawer__content mdc-list">
      <a class="mdc-list-item mdc-temporary-drawer--selected" href="#">
        <i class="material-icons mdc-list-item__start-detail" aria-hidden="true">inbox</i>Inbox
      </a>
      <a class="mdc-list-item" href="#">
        <i class="material-icons mdc-list-item__start-detail" aria-hidden="true">star</i>Star
      </a>
    </nav>
  </nav>
</aside>

CSS classes:

Class	Description
mdc-temporary-drawer	Mandatory. Needs to be set on the root element of the component.
mdc-temporary-drawer__drawer	Mandatory. Needs to be set on the container node for the drawer content.
mdc-temporary-drawer__content	Optional. Should be set on the list of items inside the drawer.
mdc-temporary-drawer__toolbar-spacer	Optional. Add to node to provide the matching amount of space for toolbar.
mdc-temporary-drawer__header	Optional. Add to container node to create a 16:9 drawer header.

Using the JS Component

MDC Temporary Drawer ships with a Component / Foundation combo which allows for frameworks to richly integrate the correct drawer behaviors into idiomatic components.

Including in code

ES2015

import {MDCTemporaryDrawer, MDCTemporaryDrawerFoundation, util} from 'mdc-drawer';

CommonJS

const mdcDrawer = require('mdc-drawer');
const MDCTemporaryDrawer = mdcDrawer.MDCTemporaryDrawer;
const MDCTemporaryDrawerFoundation = mdcDrawer.MDCTemporaryDrawerFoundation;
const util = mdcDrawer.util;

AMD

require(['path/to/mdc-drawer'], mdcDrawer => {
  const MDCTemporaryDrawer = mdcDrawer.MDCTemporaryDrawer;
  const MDCTemporaryDrawerFoundation = mdcDrawer.MDCTemporaryDrawerFoundation;
  const util = mdcDrawer.util;
});

Global

const MDCTemporaryDrawer = mdc.drawer.MDCTemporaryDrawer;
const MDCTemporaryDrawerFoundation = mdc.drawer.MDCTemporaryDrawerFoundation;
const util = mdc.drawer.util;

Automatic Instantiation

If you do not care about retaining the component instance for the temporary drawer, simply call attachTo() and pass it a DOM element.

mdc.drawer.MDCTemporaryDrawer.attachTo(document.querySelector('.mdc-temporary-drawer'));

Manual Instantiation

Temporary drawers can easily be initialized using their default constructors as well, similar to attachTo.

import {MDCTemporaryDrawer} from 'mdc-drawer';

const drawer = new MDCTemporaryDrawer(document.querySelector('.mdc-temporary-drawer'));

Handling events

When the drawer is opened or closed, the component will emit a MDCTemporaryDrawer:open or MDCTemporaryDrawer:close custom event with no data attached. Events get emitted only when the drawer toggles its opened state, i.e. multiple consecutive drawer.open = true calls will result in only one MDCTemporaryDrawer:open.

Using the Foundation Class

MDC Temporary Drawer ships with an MDCTemporaryDrawerFoundation class that external frameworks and libraries can use to integrate the component. As with all foundation classes, an adapter object must be provided. The adapter for temporary drawers must provide the following functions, with correct signatures:

Method Signature	Description
addClass(className: string) => void	Adds a class to the root element.
removeClass(className: string) => void	Removes a class from the root element.
hasClass(className: string) => boolean	Returns boolean indicating whether element has a given class.

deregisterDrawerInteractionHandler(evt: string, handler: EventListener) => void	Removes an event listener from drawer container sub-element, for the specified event name.
registerTransitionEndHandler(handler: EventListener) => void	Registers an event handler to be called when a transitionend event is triggered on the drawer container sub-element element.
deregisterTransitionEndHandler(handler: EventListener) => void	Deregisters an event handler from a transitionend event listener. This will only be called with handlers that have previously been passed to registerTransitionEndHandler calls.
registerDocumentKeydownHandler(handler: EventListener) => void	Registers an event handler on the document object for a keydown event.
deregisterDocumentKeydownHandler(handler: EventListener) => void	Deregisters an event handler on the document object for a keydown event.

The util API

External frameworks and libraries can use the following utility methods when integrating a component.

util.remapEvent(eventName, globalObj = window) => String

Remap touch events to pointer events, if the browser doesn't support touch events.

util.getTransformPropertyName(globalObj = window, forceRefresh = false) => String

Choose the correct transform property to use on the current browser.

util.supportsCssCustomProperties(globalObj = window) => Boolean

Determine whether the current browser supports CSS properties.

util.applyPassive(globalObj = window, forceRefresh = false) => object

Determine whether the current browser supports passive event listeners, and if so, use them.

util.saveElementTabState(el) => void

Save the tab state for an element.

util.restoreElementTabState(el) => void

Restore the tab state for an element, if it was saved.
