Plugins can be included individually (using Bootstrap’s individual js/dist/*.js ), or all at once using bootstrap.js or the minified bootstrap.min.js (don’t include both).

If you use a bundler (Webpack, Parcel, Vite…), you can use /js/dist/*.js files which are UMD ready.

While the Bootstrap CSS can be used with any framework, the Bootstrap JavaScript is not fully compatible with JavaScript frameworks like React, Vue, and Angular which assume full knowledge of the DOM. Both Bootstrap and the framework may attempt to mutate the same DOM element, resulting in bugs like dropdowns that are stuck in the “open” position.

A better alternative for those using this type of frameworks is to use a framework-specific package instead of the Bootstrap JavaScript. Here are some of the most popular options:

Some plugins and CSS components depend on other plugins. If you include plugins individually, make sure to check for these dependencies in the docs.

Nearly all Bootstrap plugins can be enabled and configured through HTML alone with data attributes (our preferred way of using JavaScript functionality). Be sure to only use one set of data attributes on a single element (e.g., you cannot trigger a tooltip and modal from the same button.)

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}' .

Bootstrap provides custom events for most plugins’ unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. show ) is triggered at the start of an event, and its past participle form (ex. shown ) is triggered on the completion of an action.

All constructors accept an optional options object or nothing (which initiates a plugin with its default behavior):

const myModalEl = document.querySelector('#myModal')
const modal = new bootstrap.Modal(myModalEl) // initialized with defaults
const configObject = { keyboard: false }
const modal1 = new bootstrap.Modal(myModalEl, configObject) // initialized with no keyboard

If you’d like to get a particular plugin instance, each plugin exposes a getInstance method. For example, to retrieve an instance directly from an element:

bootstrap.Popover.getInstance(myPopoverEl)

This method will return null if an instance is not initiated over the requested element.

Alternatively, getOrCreateInstance can be used to get the instance associated with a DOM element, or create a new one in case it wasn’t initialized.

bootstrap.Popover.getOrCreateInstance(myPopoverEl, configObject)

In case an instance wasn’t initialized, it may accept and use an optional configuration object as second argument.

All programmatic API methods are asynchronous and return to the caller once the transition is started, but before it ends . In order to execute an action once the transition is complete, you can listen to the corresponding event.

const myCollapseEl = document.querySelector('#myCollapse')
myCollapseEl.addEventListener('shown.bs.collapse', event => {
  // Action to execute once the collapsible area is expanded

In addition, a method call on a transitioning component will be ignored .

const myCarouselEl = document.querySelector('#myCarousel')
const carousel = bootstrap.Carousel.getInstance(myCarouselEl) // Retrieve a Carousel instance
myCarouselEl.addEventListener('slid.bs.carousel', event => {
  carousel.to('2') // Will slide to the slide 2 as soon as the transition to slide 1 is finished
carousel.to('1') // Will start sliding to the slide 1 and returns to the caller
carousel.to('2') // !! Will be ignored, as the transition to the slide 1 is not finished !!

While it may seem correct to use the dispose method immediately after hide() , it will lead to incorrect results. Here’s an example of the problem use:

const myModal = document.querySelector('#myModal')
myModal.hide() // it is asynchronous
myModal.addEventListener('shown.bs.hidden', event => {
  myModal.dispose()

You can change the default settings for a plugin by modifying the plugin’s Constructor.Default object:

// changes default for the modal plugin's `keyboard` option to false
bootstrap.Modal.Default.keyboard = false

Every Bootstrap plugin exposes the following methods and static properties.

Tooltips and Popovers use our built-in sanitizer to sanitize options which accept HTML.

The default allowList value is the following:

const ARIA_ATTRIBUTE_PATTERN = /^aria-[\w-]*$/i
const DefaultAllowlist = {
  // Global attributes allowed on any supplied element below.
  '*': ['class', 'dir', 'id', 'lang', 'role', ARIA_ATTRIBUTE_PATTERN],
  a: ['target', 'href', 'title', 'rel'],
  area: [],
  b: [],
  br: [],
  col: [],
  code: [],
  div: [],
  em: [],
  hr: [],
  h1: [],
  h2: [],
  h3: [],
  h4: [],
  h5: [],
  h6: [],
  i: [],
  img: ['src', 'srcset', 'alt', 'title', 'width', 'height'],
  li: [],
  ol: [],
  p: [],
  pre: [],
  s: [],
  small: [],
  span: [],
  sub: [],
  sup: [],
  strong: [],
  u: [],
  ul: []

If you want to add new values to this default allowList you can do the following:

const myDefaultAllowList = bootstrap.Tooltip.Default.allowList
// To allow table elements
myDefaultAllowList.table = []
// To allow td elements and data-bs-option attributes on td elements
myDefaultAllowList.td = ['data-bs-option']
// You can push your custom regex to validate your attributes.
// Be careful about your regular expressions being too lax
const myCustomRegex = /^data-my-app-[\w-]+/
myDefaultAllowList['*'].push(myCustomRegex)

You don’t need jQuery in Bootstrap 5 , but it’s still possible to use our components with jQuery. If Bootstrap detects jQuery in the window object, it’ll add all of our components in jQuery’s plugin system. This allows you to do the following:

$('[data-bs-toggle="tooltip"]').tooltip() // to enable tooltips, with default configuration
$('[data-bs-toggle="tooltip"]').tooltip({ boundary: 'clippingParents', customClass: 'myClass' }) // to initialize tooltips with given configuration
$('#myTooltip').tooltip('show') // to trigger `show` method

The same goes for our other components.

Sometimes it is necessary to use Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions can occasionally occur. If this happens, you may call .noConflict on the plugin you wish to revert the value of.

const bootstrapButton = $.fn.button.noConflict() // return $.fn.button to previously assigned value
$.fn.bootstrapBtn = bootstrapButton // give $().bootstrapBtn the Bootstrap functionality

Bootstrap does not officially support third-party JavaScript libraries like Prototype or jQuery UI. Despite .noConflict and namespaced events, there may be compatibility problems that you need to fix on your own.

Bootstrap will detect jQuery if jQuery is present in the window object and there is no data-bs-no-jquery attribute set on <body> . If jQuery is found, Bootstrap will emit events thanks to jQuery’s event system. So if you want to listen to Bootstrap’s events, you’ll have to use the jQuery methods ( .on , .one ) instead of addEventListener .

$('#myTab a').on('shown.bs.tab', () => {
  // do something...
