# List group
> List groups are a flexible and powerful component for displaying a series of content.
List group items can be modified and extended to support just about any content within.
They can also be used as navigation with the right modifier class.
List group items can be modified to support just about any content within.
They can also be used as navigation via various props.
```html
<b-list-group>
<b-list-group-item active>
Awesome list
</b-list-group-item>
<b-list-group-item href="#">
Action links are easy
</b-list-group-item>
<b-list-group-item>
This is a text only item
</b-list-group-item>
<b-list-group-item>Cras justo odio</b-list-group-item>
<b-list-group-item>Dapibus ac facilisis in</b-list-group-item>
<b-list-group-item>Morbi leo risus</b-list-group-item>
<b-list-group-item>Porta ac consectetur ac</b-list-group-item>
<b-list-group-item>Vestibulum at eros</b-list-group-item>
</b-list-group>
<!-- list-group.vue -->
```
## Active items
Set the `active` prop on a `<b-list-group-item>` to indicate the current active selection.
```html
<b-list-group>
<b-list-group-item>Cras justo odio</b-list-group-item>
<b-list-group-item active>Dapibus ac facilisis in</b-list-group-item>
<b-list-group-item>Morbi leo risus</b-list-group-item>
<b-list-group-item>Porta ac consectetur ac</b-list-group-item>
<b-list-group-item>Vestibulum at eros</b-list-group-item>
</b-list-group>
<!-- list-group-active.vue -->
```
## Disabled items
Set the `disabled` prop on a `<b-list-group-item>` to make it appear disabled (also works
with actionalable items. see below).
```html
<b-list-group>
<b-list-group-item disabled>Cras justo odio</b-list-group-item>
<b-list-group-item>Dapibus ac facilisis in</b-list-group-item>
<b-list-group-item>Morbi leo risus</b-list-group-item>
<b-list-group-item disabled>Porta ac consectetur ac</b-list-group-item>
<b-list-group-item>Vestibulum at eros</b-list-group-item>
</b-list-group>
<!-- list-group-disabled.vue -->
```
## Actionable list group items
Turn a `<b-list-group-item>` into an actionable link by specifying either an
`href` prop or router link `to` prop.
`href` prop or [router-link](/dics/reference/router-links) `to` prop.
```html
<b-list-group>
<b-list-group-item href="#some-link">Awesome link</b-list-group-item>
<b-list-group-item href="#" active>Link with active state</b-list-group-item>
<b-list-group-item href="#">Action links are easy</b-list-group-item>
<b-list-group-item href="#foobar" disabled>Disabled link</b-list-group-item>
</b-list-group>
<!-- list-group-link.vue -->
```
Or if you prefer `<buttons>` over links, set the `button` prop to `true`.
```html
<b-list-group>
<b-list-group-item button>Button item</b-list-group-item>
<b-list-group-item button>I am a button</b-list-group-item>
<b-list-group-item button disabled>Disabled button</b-list-group-item>
<b-list-group-item button>This is a button too</b-list-group-item>
</b-list-group>
<!-- list-group-button.vue -->
```
**Notes:**
- When the prop `button` is `true`, all [link replated props](/docs/components/link)
(other than `active`) and the `tag` prop will have no effect.
- When rendered as a `<button>`, and the `active` prop is set to `true`, the button will lack
any hover or focus styling due to an issue with Bootstrap V4.beta.2 CSS)
- When `href` or `to` are set, the `tag` prop has no effect.
## Contextual variants
Use contextual variants to style list items with a stateful background and color, via
the `variant` prop.
```html
<b-list-group>
<b-list-group-item>This is a default list group item</b-list-group-item>
<b-list-group-item variant="primary">This is a primary list group item</b-list-group-item>
<b-list-group-item variant="secondary">This is a secondary list group item</b-list-group-item>
<b-list-group-item variant="success">This is a success list group item</b-list-group-item>
<b-list-group-item variant="danger">This is a danger list group item</b-list-group-item>
<b-list-group-item variant="warning">This is a warning list group item</b-list-group-item>
<b-list-group-item variant="info">This is a info list group item</b-list-group-item>
<b-list-group-item variant="light">This is a light list group item</b-list-group-item>
<b-list-group-item variant="dark">This is a dark list group item</b-list-group-item>
</b-list-group>
<!-- list-group-variant.vue -->
```
Contextual variants also work with action items. Note the addition of the hover styling
here not present in the previous example. Also supported is the `active` state; set it to
indicate an active selection on a contextual list group item.
```html
<b-list-group>
<b-list-group-item href="#">This is a default list group item</b-list-group-item>
<b-list-group-item href="#" variant="primary">This is a primary list group item</b-list-group-item>
<b-list-group-item href="#" variant="secondary">This is a secondary list group item</b-list-group-item>
<b-list-group-item href="#" variant="success">This is a success list group item</b-list-group-item>
<b-list-group-item href="#" variant="danger">This is a danger list group item</b-list-group-item>
<b-list-group-item href="#" variant="warning">This is a warning list group item</b-list-group-item>
<b-list-group-item href="#" variant="info">This is a info list group item</b-list-group-item>
<b-list-group-item href="#" variant="light">This is a light list group item</b-list-group-item>
<b-list-group-item href="#" variant="dark">This is a dark list group item</b-list-group-item>
</b-list-group>
<!-- list-group-variant-action.vue -->
```
### Conveying meaning to assistive technologies
Using color to add meaning only provides a visual indication, which will not be conveyed to users
of assistive technologies – such as screen readers. Ensure that information denoted by the color
is either obvious from the content itself (e.g. the visible text), or is included through alternative
means, such as additional text hidden using the `.sr-only` class.
## With badges
Add [badges](/docs/components/badge) to any list group item to show unread counts, activity, and
more with the help of some [utility classes](http://getbootstrap.com/docs/4.0/utilities/flex/).
```html
<b-list-group>
<b-list-group-item class="d-flex justify-content-between align-items-center">
Cras justo odio
<b-badge variant="primary" pill>14</b-badge>
</b-list-group-item>
<b-list-group-item class="d-flex justify-content-between align-items-center">
Dapibus ac facilisis in
<b-badge variant="primary" pill>2</b-badge>
</b-list-group-item>
<b-list-group-item class="d-flex justify-content-between align-items-center">
Morbi leo risus
<b-badge variant="primary" pill>1</b-badge>
</b-list-group-item>
</b-list-group>
<!-- list-group-badges.vue -->
```
## List groups inside cards
Incorporate list groups into [cards](/docs/components/cards). Use the `<b-list-group>`
prop `flush` prop when using cards with `no-body` to make the sides of the list group
flush with the card.
```html
<b-card-group deck>
<b-card header="<b>Card with list group</b>">
<b-list-group>
<b-list-group-item href="#">Cras justo odio</b-list-group-item>
<b-list-group-item href="#">Dapibus ac facilisis in</b-list-group-item>
<b-list-group-item href="#">Vestibulum at eros</b-list-group-item>
</b-list-group>
<p class="card-text mt-2">
Quis magna Lorem anim amet ipsum do mollit sit cillum voluptate ex
nulla tempor. Laborum consequat non elit enim exercitation cillum aliqua
consequat id aliqua. Esse ex consectetur mollit voluptate est in duis laboris
ad sit ipsum anim Lorem.
</p>
</b-card>
<b-card no-body header="<b>Card with flush list group</b>">
<b-list-group flush>
<b-list-group-item href="#">Cras justo odio</b-list-group-item>
<b-list-group-item href="#">Dapibus ac facilisis in</b-list-group-item>
<b-list-group-item href="#">Vestibulum at eros</b-list-group-item>
</b-list-group>
<b-card-body>
Quis magna Lorem anim amet ipsum do mollit sit cillum voluptate ex
nulla tempor. Laborum consequat non elit enim exercitation cillum aliqua
consequat id aliqua. Esse ex consectetur mollit voluptate est in duis laboris
ad sit ipsum anim Lorem.
</b-card-body>
</b-card>
</b-card group>
<!-- list-group-card.vue -->
```
## Custom content
Add nearly any HTML or component within, even for linked list groups like the one below, with
the help of [flexbox utility classes](http://getbootstrap.com/docs/4.0/utilities/flex/).
```html
<b-list-group>
<b-list-group-item href="#" active class="flex-column align-items-start">
<div class="d-flex w-100 justify-content-between">
<h5 class="mb-1">List group item heading</h5>
<small>3 days ago</small>
</div>
<p class="mb-1">
Donec id elit non mi porta gravida at eget metus. Maecenas
sed diam eget risus varius blandit.
</p>
<small>Donec id elit non mi porta.</small>
</b-list-group-item>
<b-list-group-item href="#" class="flex-column align-items-start">
<div class="d-flex w-100 justify-content-between">
<h5 class="mb-1">List group item heading</h5>
<small class="text-muted">3 days ago</small>
</div>
<p class="mb-1">
Donec id elit non mi porta gravida at eget metus. Maecenas
sed diam eget risus varius blandit.
</p>
<small class="text-muted">Donec id elit non mi porta.</small>
</b-list-group-item>
<b-list-group-item href="#" disabled class="flex-column align-items-start">
<div class="d-flex w-100 justify-content-between">
<h5 class="mb-1">Disabled List group item</h5>
<small class="text-muted">3 days ago</small>
</div>
<p class="mb-1">
Donec id elit non mi porta gravida at eget metus. Maecenas
sed diam eget risus varius blandit.
</p>
<small class="text-muted">Donec id elit non mi porta.</small>
</b-list-group-item>
</b-list-group>
