Bootstrap 5 Offcanvas component

Responsive offcanvas/drawer built with the latest Bootstrap 5. Offcanvas component used for hidden sidebar on the page for navigation, shopping carts etc.

Examples for build hidden sidebars into your project for navigation, shopping carts, and more with a few classes and our JavaScript plugin.

Basic offcanvas example

Offcanvas includes support for a header with a close button and an optional body class for some initial padding. We suggest that you include offcanvas headers with dismiss actions whenever possible, or provide an explicit dismiss action.

You can use a link with the href attribute, or a button with the data-bs-target attribute. In both cases, the data-bs-toggle="offcanvas" is required.

Show offcanvas

Some text as placeholder. In real life you can have the elements you have chosen. Like, text, images, lists, etc.

<a class="btn btn-link" data-bs-toggle="offcanvas" href="#offcanvasExample" role="button" aria-controls="offcanvasExample">
  Show offcanvas
</a>
<button class="btn btn-primary" type="button" data-bs-toggle="offcanvas" data-bs-target="#offcanvasExample" aria-controls="offcanvasExample">
  Show offcanvas
</button>
<div class="offcanvas offcanvas-start" tabindex="-1" id="offcanvasExample" aria-labelledby="offcanvasExampleLabel">
  <div class="offcanvas-header">
    <h5 class="offcanvas-title" id="offcanvasExampleLabel">Offcanvas</h5>
    <button type="button" class="btn-close" data-bs-dismiss="offcanvas" aria-label="Close"></button>
  </div>
  <div class="offcanvas-body">
      Some text as placeholder. In real life you can have the elements 
      you have chosen. Like, text, images, lists, etc.
  </div>
</div>

Dark offcanvas

Change the appearance of offcanvases with utilities to better match them to different contexts like dark navbars.

In this example below we add .text-bg-dark to the .offcanvas and .btn-close-white to .btn-close for proper styling with a dark offcanvas. If you have dropdowns within, consider also adding .dropdown-menu-dark to .dropdown-menu.

Some text as placeholder. In real life you can have the elements you have chosen. Like, text, images, lists, etc.

<button class="btn btn-primary" type="button" data-bs-toggle="offcanvas" data-bs-target="#offcanvasDark" aria-controls="offcanvasDark">
  Dark offcanvas
</button>
<div class="offcanvas offcanvas-start text-bg-dark" tabindex="-1" id="offcanvasDark" aria-labelledby="offcanvasDarkLabel">
  <div class="offcanvas-header">
    <h5 class="offcanvas-title" id="offcanvasDarkLabel">Offcanvas</h5>
    <button type="button" class="btn-close btn-close-white" data-bs-dismiss="offcanvas" aria-label="Close"></button>
  </div>
  <div class="offcanvas-body">
    Some text as placeholder. In real life you can have the elements you have chosen. 
    Like, text, images, lists, etc.
  </div>
</div>

Scrolling

Body scrolling

Scrolling the <body> element is disabled when an offcanvas and its backdrop are visible. Use the data-bs-scroll="true" attribute to enable <body> scrolling.

Try scrolling the rest of the page to see this option in action.

<button class="btn btn-primary" type="button" data-bs-toggle="offcanvas" data-bs-target="#offcanvasScrolling" aria-controls="offcanvasScrolling">Enable body scrolling</button>
<div class="offcanvas offcanvas-start" data-bs-scroll="true" data-bs-backdrop="false" tabindex="-1" id="offcanvasScrolling" aria-labelledby="offcanvasScrollingLabel">
  <div class="offcanvas-header">
    <h5 class="offcanvas-title" id="offcanvasScrollingLabel">Offcanvas with body scrolling</h5>
    <button type="button" class="btn-close" data-bs-dismiss="offcanvas" aria-label="Close"></button>
  </div>
  <div class="offcanvas-body">
    <p>Try scrolling the rest of the page to see this option in action.</p>
  </div>
</div>

Body scrolling with backdrop

You can also enablescrolling with a visible backdrop by disabled the data-bs-backdrop attribute or set data-bs-backdrop="true".

Try scrolling the rest of the page to see this option in action.

<button class="btn btn-primary" type="button" data-bs-toggle="offcanvas" data-bs-target="#offcanvasWithBothOptions" aria-controls="offcanvasWithBothOptions">
  Enable both scrolling & backdrop
</button>
<div class="offcanvas offcanvas-start" data-bs-scroll="true" tabindex="-1" id="offcanvasWithBothOptions" aria-labelledby="offcanvasWithBothOptionsLabel">
  <div class="offcanvas-header">
    <h5 class="offcanvas-title" id="offcanvasWithBothOptionsLabel">Backdrop with scrolling</h5>
    <button type="button" class="btn-close" data-bs-dismiss="offcanvas" aria-label="Close"></button>
  </div>
  <div class="offcanvas-body">
    <p>Try scrolling the rest of the page to see this option in action.</p>
  </div>
</div>

Static backdrop

When backdrop is set to static, the offcanvas will not close when clicking outside of it.

I will not close if you click outside of me.

<button class="btn btn-primary" type="button" data-bs-toggle="offcanvas" data-bs-target="#staticBackdrop" aria-controls="staticBackdrop">
  Static offcanvas
</button>
<div class="offcanvas offcanvas-start" data-bs-backdrop="static" tabindex="-1" id="staticBackdrop" aria-labelledby="staticBackdropLabel">
  <div class="offcanvas-header">
    <h5 class="offcanvas-title" id="staticBackdropLabel">Offcanvas</h5>
    <button type="button" class="btn-close" data-bs-dismiss="offcanvas" aria-label="Close"></button>
  </div>
  <div class="offcanvas-body">
    <div>
      I will not close if you click outside of me.
    </div>
  </div>
</div>

Placement

There’s no default placement for offcanvas components, so you must add one of the modifier classes below.

.offcanvas-start places offcanvas on the left of the viewport (shown above)
.offcanvas-end places offcanvas on the right of the viewport
.offcanvas-top places offcanvas on the top of the viewport
.offcanvas-bottom places offcanvas on the bottom of the viewport

Try the top, right, and bottom examples out below.

Responsive

Responsive offcanvas classes hide content outside the viewport from a specified breakpoint and down. Above that breakpoint, the contents within will behave as usual.

For example, .offcanvas-lg hides content in an offcanvas below the lg breakpoint, but shows the content above the lg breakpoint.

Resize your browser to show the responsive offcanvas toggle.

This is content within an .offcanvas-lg.

<button class="btn btn-primary d-lg-none" type="button" data-bs-toggle="offcanvas" data-bs-target="#offcanvasResponsive" aria-controls="offcanvasResponsive">
  Toggle offcanvas
</button>
<div class="alert alert-info d-none d-lg-block">
  Resize your browser to show the responsive offcanvas toggle.
</div>
<div class="offcanvas-lg offcanvas-end" tabindex="-1" id="offcanvasResponsive" aria-labelledby="offcanvasResponsiveLabel">
  <div class="offcanvas-header">
    <h5 class="offcanvas-title" id="offcanvasResponsiveLabel">Responsive offcanvas</h5>
    <button type="button" class="btn-close" data-bs-dismiss="offcanvas" data-bs-target="#offcanvasResponsive" aria-label="Close"></button>
  </div>
  <div class="offcanvas-body">
    <p class="mb-0">
      This is content within an <code>.offcanvas-lg</code>.
    </p>
  </div>
</div>

Responsive offcanvas classes are available across for each breakpoint.

.offcanvas
.offcanvas-sm
.offcanvas-md
.offcanvas-lg
.offcanvas-xl
.offcanvas-xxl

Accessibility

Since the offcanvas panel is conceptually a modal dialog, be sure to add aria-labelledby="...", referencing the offcanvas title—to .offcanvas. Note that you don’t need to add role="dialog" since we already add it via JavaScript.

Modal

Contents

Usage

The offcanvas plugin utilizes a few classes and attributes to handle the heavy lifting:

.offcanvas hides the content
.offcanvas.show shows the content
.offcanvas-start hides the offcanvas on the left
.offcanvas-end hides the offcanvas on the right
.offcanvas-top hides the offcanvas on the top
.offcanvas-bottom hides the offcanvas on the bottom

Add a dismiss button with the data-bs-dismiss="offcanvas" attribute, which triggers the JavaScript functionality. Be sure to use the <button> element with it for proper behavior across all devices.

Via data attributes

Toggle

Add data-bs-toggle="offcanvas" and a data-bs-target or href to the element to automatically assign control of one offcanvas element. The data-bs-target attribute accepts a CSS selector to apply the offcanvas to. Be sure to add the class offcanvas to the offcanvas element. If you’d like it to default open, add the additional class show.

Dismiss

Dismissal can be achieved with the data attribute on a button within the offcanvas as demonstrated below:

<button type="button" class="btn-close" data-bs-dismiss="offcanvas" aria-label="Close"></button>

or on a button outside the offcanvas using the data-bs-target as demonstrated below:

<button type="button" class="btn-close" data-bs-dismiss="offcanvas" data-bs-target="#my-offcanvas" aria-label="Close"></button>

While both ways to dismiss an offcanvas are supported, keep in mind that dismissing from outside an offcanvas does not match the ARIA Authoring Practices Guide dialog (modal) pattern. Do this at your own risk.

Via JavaScript

Enable manually with:

const offcanvasElementList = document.querySelectorAll('.offcanvas')
const offcanvasList = [...offcanvasElementList].map(offcanvasEl => new bootstrap.Offcanvas(offcanvasEl))

Options

As options can be passed via data attributes or JavaScript, you can append an option name to data-bs-, as in data-bs-animation="{value}". Make sure to change the case type of the option name from “camelCase” to “kebab-case” when passing the options via data attributes. For example, use data-bs-custom-class="beautifier" instead of data-bs-customClass="beautifier".

As of Bootstrap 5.2.0, all components support an experimental reserved data attribute data-bs-config that can house simple component configuration as a JSON string. When an element has data-bs-config='{"delay":0, "title":123}' and data-bs-title="456" attributes, the final title value will be 456 and the separate data attributes will override values given on data-bs-config. In addition, existing data attributes are able to house JSON values like data-bs-delay='{"show":0,"hide":150}'.

Name	Type	Default	Description
`backdrop`	boolean or the string `static`	`true`	Apply a backdrop on body while offcanvas is open. Alternatively, specify `static` for a backdrop which doesn’t close the offcanvas when clicked.
`keyboard`	boolean	`true`	Closes the offcanvas when escape key is pressed
`scroll`	boolean	`false`	Allow body scrolling while offcanvas is open

Methods

Asynchronous methods and transitions

All API methods are asynchronous and start a transition. They return to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored.

Activates your content as an offcanvas element. Accepts an optional options object.

You can create an offcanvas instance with the constructor, for example:

const bsOffcanvas = new bootstrap.Offcanvas('#myOffcanvas')

Method	Description
`getInstance`	Static method which allows you to get the offcanvas instance associated with a DOM element
`getOrCreateInstance`	Static method which allows you to get the offcanvas instance associated with a DOM element, or create a new one in case it wasn’t initialized
`hide`	Hides an offcanvas element. Returns to the caller before the offcanvas element has actually been hidden (i.e. before the `hidden.bs.offcanvas` event occurs).
`show`	Shows an offcanvas element. Returns to the caller before the offcanvas element has actually been shown (i.e. before the `shown.bs.offcanvas` event occurs).
`toggle`	Toggles an offcanvas element to shown or hidden. Returns to the caller before the offcanvas element has actually been shown or hidden (i.e. before the `shown.bs.offcanvas` or `hidden.bs.offcanvas` event occurs).

Events

Bootstrap’s offcanvas class exposes a few events for hooking into offcanvas functionality.

Event type	Description
`hide.bs.offcanvas`	This event is fired immediately when the `hide` method has been called.
`hidden.bs.offcanvas`	This event is fired when an offcanvas element has been hidden from the user (will wait for CSS transitions to complete).
`hidePrevented.bs.offcanvas`	This event is fired when the offcanvas is shown, its backdrop is `static` and a click outside of the offcanvas is performed. The event is also fired when the escape key is pressed and the `keyboard` option is set to `false`.
`show.bs.offcanvas`	This event fires immediately when the `show` instance method is called.
`shown.bs.offcanvas`	This event is fired when an offcanvas element has been made visible to the user (will wait for CSS transitions to complete).

const myOffcanvas = document.getElementById('myOffcanvas')
myOffcanvas.addEventListener('hidden.bs.offcanvas', event => {
  // do something...
})
