Tabs

Tabs organize content into multiple sections on the same page and allow users to navigate between them.

Bootstrap 5 Tabs component

Responsive tabs build with the latest Bootstrap 5.

Tabs used to alternate among related views within the same context on the same page and without leaving the page.

Basic example

Basic tabs includes two sections - The list of nav button and the content on tab panels.

Fixed tabs

Full width

To proportionately fill all available space with your .nav-items, use .nav-fill. Notice that all horizontal space is occupied, but not every nav item has the same width.

<ul class="nav nav-fill nav-tabs mb-3" role="tablist">
  <li class="nav-item" role="presentation">
    <a class="nav-link active" id="fill-tab-0" data-bs-toggle="tab" href="#fill-tabpanel-0" role="tab" aria-controls="fill-tabpanel-0" aria-selected="true"> Tab 1 </a>
  </li>
  <li class="nav-item" role="presentation">
    <a class="nav-link" id="fill-tab-1" data-bs-toggle="tab" href="#fill-tabpanel-1" role="tab" aria-controls="fill-tabpanel-1" aria-selected="false"> Tab 2 </a>
  </li>
  <li class="nav-item" role="presentation">
    <a class="nav-link" id="fill-tab-2" data-bs-toggle="tab" href="#fill-tabpanel-2" role="tab" aria-controls="fill-tabpanel-2" aria-selected="false"> Tab 3 </a>
  </li>
</ul>
<div class="tab-content" id="tab-content">
  <div class="tab-pane active" id="fill-tabpanel-0" role="tabpanel" aria-labelledby="fill-tab-0">One</div>
  <div class="tab-pane" id="fill-tabpanel-1" role="tabpanel" aria-labelledby="fill-tab-1">Two</div>
  <div class="tab-pane" id="fill-tabpanel-2" role="tabpanel" aria-labelledby="fill-tab-2">Three</div>
</div>

For equal-width elements, use .nav-justified. All horizontal space will be occupied by nav links, but unlike the .nav-fill above, every nav item will be the same width.

<ul class="nav nav-tabs nav-justified mb-3" role="tablist">

  <div class="tab-pane" id="justified-tabpanel-2" role="tabpanel" aria-labelledby="justified-tab-2">Three</div>
</div>

Centered

To make centered tabs use the .justify-content-center utility.

<ul class="nav nav-tabs justify-content-center" role="tablist">
  <li class="nav-item" role="presentation">
    <a class="nav-link active" data-bs-toggle="tab" href="#" role="tab"> Tab 1 </a>
  </li>
  <li class="nav-item" role="presentation">
    <a class="nav-link" data-bs-toggle="tab" href="#" role="tab"> Tab 2 </a>
  </li>
  <li class="nav-item" role="presentation">
    <a class="nav-link" data-bs-toggle="tab" href="#" role="tab"> Tab 3 </a>
  </li>
</ul>

Vertical tabs

To make vertical tabs instead of default horizontal ones, add .nav-tabs-vertical to the .nav-tabs. For vertical tabs, you should also add aria-orientation="vertical" to the tab list container.

Tabs with dropdowns

Add dropdown menus into the .nav-link.

<ul class="nav nav-tabs" role="tablist">
  <li class="nav-item" role="presentation">
    <a class="nav-link active" data-bs-toggle="tab" href="#" role="tab"> Tab 1 </a>
  </li>
  <li class="nav-item" role="presentation">
    <a class="nav-link" data-bs-toggle="tab" href="#" role="tab"> Tab 2 </a>
  </li>
  <li class="nav-item" role="presentation">
    <a class="nav-link" data-bs-toggle="dropdown" href="#" role="button" aria-expanded="false">
      <span class="dropdown-toggle"> Dropdown </span>
    </a>
    <ul class="dropdown-menu">
      <li><a class="dropdown-item" href="#">Action</a></li>
      <li><a class="dropdown-item" href="#">Another action</a></li>
      <li><a class="dropdown-item" href="#">Something else here</a></li>
      <li><hr class="dropdown-divider" /></li>
      <li><a class="dropdown-item" href="#">Separated link</a></li>
    </ul>
  </li>
</ul>

Accessibility

(WAI-ARIA: https://www.w3.org/WAI/ARIA/apg/patterns/tabpanel/)

Dynamic tabbed interfaces, as described in the ARIA Authoring Practices Guide tabs pattern, require role="tablist", role="tab", role="tabpanel", and additional aria- attributes in order to convey their structure, functionality, and current state to users of assistive technologies (such as screen readers). As a best practice, we recommend using <button> elements for the tabs, as these are controls that trigger a dynamic change, rather than links that navigate to a new page or location.

In line with the ARIA Authoring Practices pattern, only the currently active tab receives keyboard focus. When the JavaScript plugin is initialized, it will set tabindex="-1" on all inactive tab controls. Once the currently active tab has focus, the cursor keys activate the previous/next tab, with the plugin changing the roving tabindex accordingly. However, note that the JavaScript plugin does not distinguish between horizontal and vertical tab lists when it comes to cursor key interactions: regardless of the tab list’s orientation, both the up and left cursor go to the previous tab, and down and right cursor go to the next tab.

In general, to facilitate keyboard navigation, it’s recommended to make the tab panels themselves focusable as well, unless the first element containing meaningful content inside the tab panel is already focusable. The JavaScript plugin does not try to handle this aspect—where appropriate, you’ll need to explicitly make your tab panels focusable by adding tabindex="0" in your markup.

The tab JavaScript plugin does not support tabbed interfaces that contain dropdown menus, as these cause both usability and accessibility issues. From a usability perspective, the fact that the currently displayed tab’s trigger element is not immediately visible (as it’s inside the closed dropdown menu) can cause confusion. From an accessibility point of view, there is currently no sensible way to map this sort of construct to a standard WAI ARIA pattern, meaning that it cannot be easily made understandable to users of assistive technologies.

Usage

Using data attributes

You can activate a tab navigation without writing any JavaScript by simply specifying data-bs-toggle="tab" on an element. Use these data attributes on .nav-tabs.

<!-- Nav tabs -->
<ul class="nav nav-tabs" id="myTab" role="tablist">
  <li class="nav-item" role="presentation">
    <button class="nav-link active" id="home-tab" data-bs-toggle="tab" data-bs-target="#home" type="button" role="tab" aria-controls="home" aria-selected="true">Home</button>
  </li>
  <li class="nav-item" role="presentation">
    <button class="nav-link" id="profile-tab" data-bs-toggle="tab" data-bs-target="#profile" type="button" role="tab" aria-controls="profile" aria-selected="false">Profile</button>
  </li>
  <li class="nav-item" role="presentation">
    <button class="nav-link" id="messages-tab" data-bs-toggle="tab" data-bs-target="#messages" type="button" role="tab" aria-controls="messages" aria-selected="false">Messages</button>
  </li>
  <li class="nav-item" role="presentation">
    <button class="nav-link" id="settings-tab" data-bs-toggle="tab" data-bs-target="#settings" type="button" role="tab" aria-controls="settings" aria-selected="false">Settings</button>
  </li>
</ul>

<!-- Tab panes -->
<div class="tab-content">
  <div class="tab-pane active" id="home" role="tabpanel" aria-labelledby="home-tab" tabindex="0">...</div>
  <div class="tab-pane" id="profile" role="tabpanel" aria-labelledby="profile-tab" tabindex="0">...</div>
  <div class="tab-pane" id="messages" role="tabpanel" aria-labelledby="messages-tab" tabindex="0">...</div>
  <div class="tab-pane" id="settings" role="tabpanel" aria-labelledby="settings-tab" tabindex="0">...</div>
</div>

Via JavaScript

Enable tabbable tabs via JavaScript (each tab needs to be activated individually):

const triggerTabList = document.querySelectorAll('#myTab button')
triggerTabList.forEach(triggerEl => {
  const tabTrigger = new bootstrap.Tab(triggerEl)

  triggerEl.addEventListener('click', event => {
    event.preventDefault()
    tabTrigger.show()
  })
})

You can activate individual tabs in several ways:

const triggerEl = document.querySelector('#myTab button[data-bs-target="#profile"]')
bootstrap.Tab.getInstance(triggerEl).show() // Select tab by name

const triggerFirstTabEl = document.querySelector('#myTab li:first-child button')
bootstrap.Tab.getInstance(triggerFirstTabEl).show() // Select first tab

Fade effect

To make tabs fade in, add .fade to each .tab-pane. The first tab pane must also have .show to make the initial content visible.

<div class="tab-content">
  <div class="tab-pane fade show active" id="home" role="tabpanel" aria-labelledby="home-tab" tabindex="0">...</div>
  <div class="tab-pane fade" id="profile" role="tabpanel" aria-labelledby="profile-tab" tabindex="0">...</div>
  <div class="tab-pane fade" id="messages" role="tabpanel" aria-labelledby="messages-tab" tabindex="0">...</div>
  <div class="tab-pane fade" id="settings" role="tabpanel" aria-labelledby="settings-tab" tabindex="0">...</div>
</div>

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.

constructor

Activates a tab element and content container. Tab should have either a data-bs-target or, if using a link, an href attribute, targeting a container node in the DOM.

<ul class="nav nav-tabs" id="myTab" role="tablist">
  <li class="nav-item" role="presentation">
    <button class="nav-link active" id="home-tab" data-bs-toggle="tab" data-bs-target="#home" type="button" role="tab" aria-controls="home" aria-selected="true">Home</button>
  </li>
  <li class="nav-item" role="presentation">
    <button class="nav-link" id="profile-tab" data-bs-toggle="tab" data-bs-target="#profile" type="button" role="tab" aria-controls="profile" aria-selected="false">Profile</button>
  </li>
  <li class="nav-item" role="presentation">
    <button class="nav-link" id="messages-tab" data-bs-toggle="tab" data-bs-target="#messages" type="button" role="tab" aria-controls="messages" aria-selected="false">Messages</button>
  </li>
  <li class="nav-item" role="presentation">
    <button class="nav-link" id="settings-tab" data-bs-toggle="tab" data-bs-target="#settings" type="button" role="tab" aria-controls="settings" aria-selected="false">Settings</button>
  </li>
</ul>

<div class="tab-content">
  <div class="tab-pane active" id="home" role="tabpanel" aria-labelledby="home-tab" tabindex="0">...</div>
  <div class="tab-pane" id="profile" role="tabpanel" aria-labelledby="profile-tab" tabindex="0">...</div>
  <div class="tab-pane" id="messages" role="tabpanel" aria-labelledby="messages-tab" tabindex="0">...</div>
  <div class="tab-pane" id="settings" role="tabpanel" aria-labelledby="settings-tab" tabindex="0">...</div>
</div>

<script>
  const firstTabEl = document.querySelector('#myTab li:last-child button')
  const firstTab = new bootstrap.Tab(firstTabEl)

  firstTab.show()
</script>

show

Selects the given tab and shows its associated pane. Any other tab that was previously selected becomes unselected and its associated pane is hidden. Returns to the caller before the tab pane has actually been shown (i.e. before the shown.bs.tab event occurs).

const someTabTriggerEl = document.querySelector('#someTabTrigger')
const tab = new bootstrap.Tab(someTabTriggerEl)

tab.show()

dispose

Destroys an element’s tab.

getInstance

Static method which allows you to get the tab instance associated with a DOM element

const tab = bootstrap.Tab.getInstance('#trigger') // Returns a Bootstrap tab instance

getOrCreateInstance

Static method which allows you to get the tab instance associated with a DOM element, or create a new one in case it wasn’t initialized

const tab = bootstrap.Tab.getOrCreateInstance('#trigger') // Returns a Bootstrap tab instance

Events

When showing a new tab, the events fire in the following order:

hide.bs.tab (on the current active tab)
show.bs.tab (on the to-be-shown tab)
hidden.bs.tab (on the previous active tab, the same one as for the hide.bs.tab event)
shown.bs.tab (on the newly-active just-shown tab, the same one as for the show.bs.tab event)

If no tab was already active, then the hide.bs.tab and hidden.bs.tab events will not be fired.

Event type	Description
`hide.bs.tab`	This event fires when a new tab is to be shown (and thus the previous active tab is to be hidden). Use `event.target` and `event.relatedTarget` to target the current active tab and the new soon-to-be-active tab, respectively.
`hidden.bs.tab`	This event fires after a new tab is shown (and thus the previous active tab is hidden). Use `event.target` and `event.relatedTarget` to target the previous active tab and the new active tab, respectively.
`show.bs.tab`	This event fires on tab show, but before the new tab has been shown. Use `event.target` and `event.relatedTarget` to target the active tab and the previous active tab (if available) respectively.
`shown.bs.tab`	This event fires on tab show after a tab has been shown. Use `event.target` and `event.relatedTarget` to target the active tab and the previous active tab (if available) respectively.

const tabEl = document.querySelector('button[data-bs-toggle="tab"]')
tabEl.addEventListener('shown.bs.tab', event => {
  event.target // newly activated tab
  event.relatedTarget // previous active tab
})
