# Navigation drawers

[Navigation drawers](https://material.io/components/navigation-drawer) provide access to destinations in your app.

* [Usage within web frameworks](#usage-within-web-frameworks)

## Using navigation drawers

A navigation drawer provides access to destinations and app functionality, such as switching accounts. It can either be permanently on-screen or controlled by a navigation menu icon.

A navigation drawer is recommended for:

* Apps with five or more top-level destinations
* Apps with two or more levels of navigation hierarchy
* Quick navigation between unrelated destinations

### Important Changes

Drawer is currently being updated to use the new List implementation. For now,
please continue to use the old implementation (`mdc-deprecated-list` and
associated DOM/classes) instead of the new one (`mdc-list`).

See the [List documentation](../mdc-list/README.md) for more information.

### Installation

```
npm install @loipham/material-drawer
```

### Styles

```scss
@use "@loipham/material-drawer";
@use "@loipham/material-list";

@include drawer.core-styles;
@include drawer.dismissible-core-styles;
@include drawer.modal-core-styles;
@include list.deprecated-core-styles;
```

### JavaScript instantiation

For permanently visible drawer, the list must be instantiated for appropriate keyboard interaction:

```js
import {MDCList} from "@loipham/material-list";
const list = MDCList.attachTo(document.querySelector('.mdc-deprecated-list'));
list.wrapFocus = true;
```

Other variants use the `MDCDrawer` component, which will instantiate `MDCList` automatically:

```js
import {MDCDrawer} from "@loipham/material-drawer";
const drawer = MDCDrawer.attachTo(document.querySelector('.mdc-drawer'));
```

### Icons

We recommend using [Material Icons](https://material.io/tools/icons/) from Google Fonts:

```html
<head>
  <link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
</head>
```

However, you can also use SVG, [Font Awesome](https://fontawesome.com/), or any other icon library you wish.

### Making navigation drawers accessible

### 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.

```js
const listEl = document.querySelector('.mdc-drawer .mdc-deprecated-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.

```js
const listEl = document.querySelector('.mdc-drawer .mdc-deprecated-list');
const mainContentEl = document.querySelector('.main-content');

listEl.addEventListener('click', (event) => {
  drawer.open = false;
});

document.body.addEventListener('MDCDrawer:closed', () => {
  mainContentEl.querySelector('input, button').focus();
});
```

## Types

There are three types of navigation drawers: [standard (1)](#standard-navigation-drawers), [modal (2)](#modal-navigation-drawers), and [bottom (3)](#bottom-navigation-drawers).

![Standard, modal, and bottom navigation drawers](images/drawer-composite.png)

### Standard navigation drawers

[Standard navigation drawers](https://material.io/components/navigation-drawer#standard-drawer) allow interaction with both screen content and the drawer at the same time. They can be used on tablet and desktop, but they aren’t suitable for mobile due to limited screen size.

```html
<aside class="mdc-drawer">
  <div class="mdc-drawer__content">
    <nav class="mdc-deprecated-list">
      <a class="mdc-deprecated-list-item mdc-deprecated-list-item--activated" href="#" aria-current="page">
        <span class="mdc-deprecated-list-item__ripple"></span>
        <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">inbox</i>
        <span class="mdc-deprecated-list-item__text">Inbox</span>
      </a>
      <a class="mdc-deprecated-list-item" href="#">
        <span class="mdc-deprecated-list-item__ripple"></span>
        <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">send</i>
        <span class="mdc-deprecated-list-item__text">Outgoing</span>
      </a>
      <a class="mdc-deprecated-list-item" href="#">
        <span class="mdc-deprecated-list-item__ripple"></span>
        <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">drafts</i>
        <span class="mdc-deprecated-list-item__text">Drafts</span>
      </a>
    </nav>
  </div>
</aside>
```

### Modal navigation drawers

[Modal navigation drawers](https://material.io/components/navigation-drawer#modal-drawer) block interaction with the rest of an app’s content with a scrim. They are elevated above most of the app’s UI and don’t affect the screen’s layout grid.


```html
<body>
  <aside class="mdc-drawer mdc-drawer--modal">
    <div class="mdc-drawer__content">
      <nav class="mdc-deprecated-list">
        <a class="mdc-deprecated-list-item mdc-deprecated-list-item--activated" href="#" aria-current="page" tabindex="0">
          <span class="mdc-deprecated-list-item__ripple"></span>
          <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">inbox</i>
          <span class="mdc-deprecated-list-item__text">Inbox</span>
        </a>
        <a class="mdc-deprecated-list-item" href="#">
          <span class="mdc-deprecated-list-item__ripple"></span>
          <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">send</i>
          <span class="mdc-deprecated-list-item__text">Outgoing</span>
        </a>
        <a class="mdc-deprecated-list-item" href="#">
          <span class="mdc-deprecated-list-item__ripple"></span>
          <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">drafts</i>
          <span class="mdc-deprecated-list-item__text">Drafts</span>
        </a>
      </nav>
    </div>
  </aside>

  <div class="mdc-drawer-scrim"></div>
  <div>Main Content</div>
</body>
```

**Note: The `mdc-drawer-scrim` next sibling element is required, to protect the app's UI from interactions while the modal drawer is open.**

### Bottom navigation drawers

[Bottom navigation drawers](https://material.io/components/navigation-drawer#bottom-drawer) are modal drawers that are anchored to the bottom of the screen instead of the left or right edge. They are only used with bottom app bars.

MDC Web does not currently support bottom navigation drawers.

## Other variants

### Drawer with separate list groups

```html
<aside class="mdc-drawer">
  <div class="mdc-drawer__content">
    <nav class="mdc-deprecated-list">
      <a class="mdc-deprecated-list-item mdc-deprecated-list-item--activated" href="#" aria-current="page">
        <span class="mdc-deprecated-list-item__ripple"></span>
        <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">inbox</i>
        <span class="mdc-deprecated-list-item__text">Inbox</span>
      </a>
      <a class="mdc-deprecated-list-item" href="#">
        <span class="mdc-deprecated-list-item__ripple"></span>
        <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">star</i>
        <span class="mdc-deprecated-list-item__text">Star</span>
      </a>
      <a class="mdc-deprecated-list-item" href="#">
        <span class="mdc-deprecated-list-item__ripple"></span>
        <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">send</i>
        <span class="mdc-deprecated-list-item__text">Sent Mail</span>
      </a>
      <a class="mdc-deprecated-list-item" href="#">
        <span class="mdc-deprecated-list-item__ripple"></span>
        <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">drafts</i>
        <span class="mdc-deprecated-list-item__text">Drafts</span>
      </a>

      <hr class="mdc-deprecated-list-divider">
      <h6 class="mdc-deprecated-list-group__subheader">Labels</h6>
      <a class="mdc-deprecated-list-item" href="#">
        <span class="mdc-deprecated-list-item__ripple"></span>
        <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">bookmark</i>
        <span class="mdc-deprecated-list-item__text">Family</span>
      </a>
      <a class="mdc-deprecated-list-item" href="#">
        <span class="mdc-deprecated-list-item__ripple"></span>
        <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">bookmark</i>
        <span class="mdc-deprecated-list-item__text">Friends</span>
      </a>
      <a class="mdc-deprecated-list-item" href="#">
        <span class="mdc-deprecated-list-item__ripple"></span>
        <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">bookmark</i>
        <span class="mdc-deprecated-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.

```html
<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-deprecated-list">
      <a class="mdc-deprecated-list-item mdc-deprecated-list-item--activated" href="#" aria-current="page">
        <span class="mdc-deprecated-list-item__ripple"></span>
        <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">inbox</i>
        <span class="mdc-deprecated-list-item__text">Inbox</span>
      </a>
      <a class="mdc-deprecated-list-item" href="#">
        <span class="mdc-deprecated-list-item__ripple"></span>
        <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">send</i>
        <span class="mdc-deprecated-list-item__text">Outgoing</span>
      </a>
      <a class="mdc-deprecated-list-item" href="#">
        <span class="mdc-deprecated-list-item__ripple"></span>
        <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">drafts</i>
        <span class="mdc-deprecated-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.

```html
<body>
  <aside class="mdc-drawer mdc-drawer--dismissible">
    <div class="mdc-drawer__content">
      <nav class="mdc-deprecated-list">
        <a class="mdc-deprecated-list-item mdc-deprecated-list-item--activated" href="#" aria-current="page">
          <span class="mdc-deprecated-list-item__ripple"></span>
          <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">inbox</i>
          <span class="mdc-deprecated-list-item__text">Inbox</span>
        </a>
        <a class="mdc-deprecated-list-item" href="#">
          <span class="mdc-deprecated-list-item__ripple"></span>
          <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">send</i>
          <span class="mdc-deprecated-list-item__text">Outgoing</span>
        </a>
        <a class="mdc-deprecated-list-item" href="#">
          <span class="mdc-deprecated-list-item__ripple"></span>
          <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">drafts</i>
          <span class="mdc-deprecated-list-item__text">Drafts</span>
        </a>
      </nav>
    </div>
  </aside>

  <div class="mdc-drawer-app-content">
    App Content
  </div>
</body>
```

**Note: 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:

```html
<body>
  <aside class="mdc-drawer mdc-drawer--dismissible">
    <div class="mdc-drawer__content">
      <div class="mdc-deprecated-list">
        <a class="mdc-deprecated-list-item mdc-deprecated-list-item--activated" href="#" aria-current="page">
          <span class="mdc-deprecated-list-item__ripple"></span>
          <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">inbox</i>
          <span class="mdc-deprecated-list-item__text">Inbox</span>
        </a>
        <a class="mdc-deprecated-list-item" href="#">
          <span class="mdc-deprecated-list-item__ripple"></span>
          <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">send</i>
          <span class="mdc-deprecated-list-item__text">Outgoing</span>
        </a>
        <a class="mdc-deprecated-list-item" href="#">
          <span class="mdc-deprecated-list-item__ripple"></span>
          <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">drafts</i>
          <span class="mdc-deprecated-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">
          <button class="material-icons mdc-top-app-bar__navigation-icon mdc-icon-button">menu</button>
          <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>
```

##### 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.

```html
<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">
        <button class="material-icons mdc-top-app-bar__navigation-icon mdc-icon-button">menu</button>
        <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-deprecated-list">
        <a class="mdc-deprecated-list-item mdc-deprecated-list-item--activated" href="#" aria-current="page">
          <span class="mdc-deprecated-list-item__ripple"></span>
          <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">inbox</i>
          <span class="mdc-deprecated-list-item__text">Inbox</span>
        </a>
        <a class="mdc-deprecated-list-item" href="#">
          <span class="mdc-deprecated-list-item__ripple"></span>
          <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">send</i>
          <span class="mdc-deprecated-list-item__text">Outgoing</span>
        </a>
        <a class="mdc-deprecated-list-item" href="#">
          <span class="mdc-deprecated-list-item__ripple"></span>
          <i class="material-icons mdc-deprecated-list-item__graphic" aria-hidden="true">drafts</i>
          <span class="mdc-deprecated-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:

```scss
// 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;
  position: relative;
}

.main-content {
  overflow: auto;
  height: 100%;
}

.app-bar {
  position: absolute;
}

// Only apply this style if below top app bar.
.mdc-top-app-bar {
  z-index: 7;
}
```

The JavaScript to toggle the drawer when the navigation button is clicked looks like this:

```js
import {MDCTopAppBar} from "@loipham/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;
});
```
