docs List group List groups are a flexible and powerful component for displaying a series of content. Modify and extend them to support just about any content within. components true

Basic example

The most basic list group is an unordered list with list items and the proper classes. Build upon it with the options that follow, or with your own CSS as needed.

{{< example >}}

  • An item
  • A second item
  • A third item
  • A fourth item
  • And a fifth one
{{< /example >}}

Active items

Add .active to a .list-group-item to indicate the current active selection.

{{< example >}}

  • An active item
  • A second item
  • A third item
  • A fourth item
  • And a fifth one
{{< /example >}}

Disabled items

Add .disabled to a .list-group-item to make it appear disabled. Note that some elements with .disabled will also require custom JavaScript to fully disable their click events (e.g., links).

{{< example >}}

  • A disabled item
  • A second item
  • A third item
  • A fourth item
  • And a fifth one
{{< /example >}}

Use <a>s or <button>s to create actionable list group items with hover, disabled, and active states by adding .list-group-item-action. We separate these pseudo-classes to ensure list groups made of non-interactive elements (like <li>s or <div>s) don't provide a click or tap affordance.

Be sure to not use the standard .btn classes here.

{{< example >}}

{{< /example >}}

With <button>s, you can also make use of the disabled attribute instead of the .disabled class. Sadly, <a>s don't support the disabled attribute.

{{< example >}}

The current button A second item A third button item A fourth button item A disabled button item
{{< /example >}}

Flush

Add .list-group-flush to remove some borders and rounded corners to render list group items edge-to-edge in a parent container (e.g., cards).

{{< example >}}

  • An item
  • A second item
  • A third item
  • A fourth item
  • And a fifth one
{{< /example >}}

Horizontal

Add .list-group-horizontal to change the layout of list group items from vertical to horizontal across all breakpoints. Alternatively, choose a responsive variant .list-group-horizontal-{sm|md|lg|xl|xxl} to make a list group horizontal starting at that breakpoint's min-width. Currently horizontal list groups cannot be combined with flush list groups.

ProTip: Want equal-width list group items when horizontal? Add .flex-fill to each list group item.

{{< example >}} {{< list-group.inline >}} {{- range $.Site.Data.breakpoints }}

  • An item
  • A second item
  • A third item
{{- end -}} {{< /list-group.inline >}} {{< /example >}}

Contextual classes

Use contextual classes to style list items with a stateful background and color.

{{< example >}}

  • A simple default list group item
  • {{< list.inline >}} {{- range (index $.Site.Data "theme-colors") }}
  • A simple {{ .name }} list group item
  • {{- end -}} {{< /list.inline >}}
{{< /example >}}

Contextual classes also work with .list-group-item-action. Note the addition of the hover styles here not present in the previous example. Also supported is the .active state; apply it to indicate an active selection on a contextual list group item.

{{< example >}}

A simple default list group item {{< list.inline >}} {{- range (index $.Site.Data "theme-colors") }} A simple {{ .name }} list group item {{- end -}} {{< /list.inline >}}
{{< /example >}}

{{< callout info >}} {{< partial "callout-warning-color-assistive-technologies.md" >}} {{< /callout >}}

With badges

Add badges to any list group item to show unread counts, activity, and more with the help of some [utilities]({{< docsref "/utilities/flex" >}}).

{{< example >}}

  • A list item 14
  • A second list item 2
  • A third list item 1
{{< /example >}}

Custom content

Add nearly any HTML within, even for linked list groups like the one below, with the help of [flexbox utilities]({{< docsref "/utilities/flex" >}}).

{{< example >}}

{{< /example >}}

Checkboxes and radios

Place Bootstrap's checkboxes and radios within list group items and customize as needed. You can use them without <label>s, but please remember to include an aria-label attribute and value for accessibility.

{{< example >}}

  • First checkbox
  • Second checkbox
  • Third checkbox
  • Fourth checkbox
  • Fifth checkbox
{{< /example >}}

And if you want <label>s as the .list-group-item for large hit areas, you can do that, too.

{{< example >}}

First checkbox Second checkbox Third checkbox Fourth checkbox Fifth checkbox
{{< /example >}}

Sass

Variables

{{< scss-docs name="list-group-variables" file="scss/_variables.scss" >}}

Mixins

Used in combination with $theme-colors to generate the contextual variant classes for .list-group-items.

{{< scss-docs name="list-group-mixin" file="scss/mixins/_list-group.scss" >}}

Loop

Loop that generates the modifier classes with the list-group-item-variant() mixin.

{{< scss-docs name="list-group-modifiers" file="scss/_list-group.scss" >}}

JavaScript behavior

Use the tab JavaScript plugin—include it individually or through the compiled bootstrap.js file—to extend our list group to create tabbable panes of local content.

Some placeholder content in a paragraph relating to "Home". And some more content, used here just to pad out and fill this tab panel. In production, you would obviously have more real content here. And not just text. It could be anything, really. Text, images, forms.

Some placeholder content in a paragraph relating to "Profile". And some more content, used here just to pad out and fill this tab panel. In production, you would obviously have more real content here. And not just text. It could be anything, really. Text, images, forms.

Some placeholder content in a paragraph relating to "Messages". And some more content, used here just to pad out and fill this tab panel. In production, you would obviously have more real content here. And not just text. It could be anything, really. Text, images, forms.

Some placeholder content in a paragraph relating to "Settings". And some more content, used here just to pad out and fill this tab panel. In production, you would obviously have more real content here. And not just text. It could be anything, really. Text, images, forms.

    </div>

</div>

Using data attributes

You can activate a list group navigation without writing any JavaScript by simply specifying data-bs-toggle="list" or on an element. Use these data attributes on .list-group-item.

<div role="tabpanel">
  <!-- List group -->
  <div class="list-group" id="myList" role="tablist">
    <a class="list-group-item list-group-item-action active" data-bs-toggle="list" href="#home" role="tab">Home</a>
    <a class="list-group-item list-group-item-action" data-bs-toggle="list" href="#profile" role="tab">Profile</a>
    <a class="list-group-item list-group-item-action" data-bs-toggle="list" href="#messages" role="tab">Messages</a>
    <a class="list-group-item list-group-item-action" data-bs-toggle="list" href="#settings" role="tab">Settings</a>
  </div>

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

Via JavaScript

Enable tabbable list item via JavaScript (each list item needs to be activated individually):

var triggerTabList = [].slice.call(document.querySelectorAll('#myTab a'))
triggerTabList.forEach(function (triggerEl) {
  var tabTrigger = new bootstrap.Tab(triggerEl)

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

You can activate individual list item in several ways:

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

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

Fade effect

To make tabs panel 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">...</div>
  <div class="tab-pane fade" id="profile" role="tabpanel">...</div>
  <div class="tab-pane fade" id="messages" role="tabpanel">...</div>
  <div class="tab-pane fade" id="settings" role="tabpanel">...</div>
</div>

Methods

constructor

Activates a list item element and content container. Tab should have either a data-bs-target or an href targeting a container node in the DOM.

<div class="list-group" id="myList" role="tablist">
  <a class="list-group-item list-group-item-action active" data-bs-toggle="list" href="#home" role="tab">Home</a>
  <a class="list-group-item list-group-item-action" data-bs-toggle="list" href="#profile" role="tab">Profile</a>
  <a class="list-group-item list-group-item-action" data-bs-toggle="list" href="#messages" role="tab">Messages</a>
  <a class="list-group-item list-group-item-action" data-bs-toggle="list" href="#settings" role="tab">Settings</a>
</div>

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

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

  firstTab.show()
</script>

show

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

  var someListItemEl = document.querySelector('#someListItem')
  var tab = new bootstrap.Tab(someListItemEl)

  tab.show()

dispose

Destroys an element's tab.

getInstance

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

var triggerEl = document.querySelector('#trigger')
var tab = bootstrap.Tab.getInstance(triggerEl) // Returns a Bootstrap tab instance

Events

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

  1. hide.bs.tab (on the current active tab)
  2. show.bs.tab (on the to-be-shown tab)
  3. hidden.bs.tab (on the previous active tab, the same one as for the hide.bs.tab event)
  4. 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, the hide.bs.tab and hidden.bs.tab events will not be fired.

Event type Description
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.
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.
var tabEl = document.querySelector('a[data-bs-toggle="list"]')
tabEl.addEventListener('shown.bs.tab', function (event) {
  event.target // newly activated tab
  event.relatedTarget // previous active tab
})
