Tabs

Bootstrap 5 Tabs component

Tabs are quasi-navigation components which can highly improve website clarity and increase user experience.

Note: Read the API tab to find all available options and advanced customization

Basic example

Basic tabs are divided into 2 main sections - Tabs navs (containing nav-items) and Tabs content (containing tab-panes).

Use id and href attribute to connect tabs navs with tabs content.

In the example below Tab 1 uses href="#ex1-tabs-1" in the first nav-link element to connect it with the first tab-pane which has an ID ex1-tabs-1.

Tab 1 content
Tab 2 content
Tab 3 content

Fill and justify

Force your .nav's contents to extend the full available width one of two modifier classes.

Fill

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.

Justify

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.

Vertical

Stack your navigation by changing the flex item direction with the .flex-column utility. Need to stack them on some viewports but not others? Use the responsive versions (e.g., .flex-sm-column).

For proper layout, you may also need to use grid to adjust navs and content.

Tabs with buttons

Dynamic tabbed interfaces, as described in the WAI ARIA Authoring Practices, 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.

Tabs - API

Usage

Regarding accessibility

If you’re using navs to provide a navigation bar, be sure to add a role="navigation" to the most logical parent container of the <ul>, or wrap a <nav> element around the whole navigation. Do not add the role to the <ul> itself, as this would prevent it from being announced as an actual list by assistive technologies.

Note that navigation bars, even if visually styled as tabs with the .nav-tabs class, should not be given role="tablist", role="tab" or role="tabpanel" attributes. These are only appropriate for dynamic tabbed interfaces, as described in the WAI ARIA Authoring Practices. The aria-current attribute is not necessary on dynamic tabbed interfaces since our JavaScript handles the selected state by adding aria-selected="true" on the active tab.

Via data attributes

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


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

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

Via JavaScript

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


          const triggerTabList = [].slice.call(document.querySelectorAll('#myTab a'));
          triggerTabList.forEach((triggerEl) => {
            const tabTrigger = new mdb.Tab(triggerEl);

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

You can activate individual tabs in several ways:


          const triggerEl = document.querySelector('#myTab a[href="#profile"]');
          mdb.Tab.getInstance(triggerEl).show(); // Select tab by name

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

Via jQuery

Note: By default, MDB does not include jQuery and you have to add it to the project on your own. 


          $('.example-class').tab();

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.

Name Description Example
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.mdb.tab event occurs). instance.show()
dispose Destroys an element’s tab. instance.dispose()
getInstance Static method which allows you to get the tab instance associated to a DOM element. Tab.getInstance(someTabTriggerEl) 

          const someTabTriggerEl = document.querySelector('#someTabTrigger');
          const tab = new mdb.Tab(someTabTriggerEl) tab.show();

Events

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

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

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

Event type Description
show.mdb.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.mdb.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.
hide.mdb.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.mdb.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. 

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

Import

MDB UI KIT also works with module bundlers. Use the following code to import this component: 


        import { Tab } from 'mdb-ui-kit';
