bootstrap-vue/src/components/button-group/README.md

BootstrapVue provides one of the most comprehensive implementations of Bootstrap 4 components and grid system for Vue.js and with extensive and automated WAI-ARIA accessibility markup.

# Button group

> Group a series of buttons together on a single line with `<b-button group>`.

**Example 1:** Default button group and button group using contextual variants
```html
<div>
  <b-button-group>
    <b-button>Button 1</b-button>
    <b-button>Button 2</b-button>
    <b-button>Button 3</b-button>
    <b-button>Button 4</b-button>
    <b-button>Button 5</b-button>
  </b-button-group>
  <br><br>
  <b-button-group>
    <b-button variant="success">Success</b-button>
    <b-button variant="info">Info</b-button>
    <b-button variant="warning">Warning</b-button>
    <b-button variant="primary">Primary</b-button>
    <b-button variant="danger">Danger</b-button>
    <b-button variant="link">Link</b-button>
  </b-button-group>
</div>

<!-- button-group-1.vue -->
```

## Sizing
Set the size prop to `lg` or `sm` to render larger or smaller, respectively, buttons.
There is no need to specify the size on the individual buttons.

**Example 2:** Default, Small, and Large button groups
```html
<div>
  <b-button-group>
    <b-button>Button 1</b-button>
    <b-button>Button 2</b-button>
    <b-button>Button 3</b-button>
  </b-button-group>
  <br><br>
  <b-button-group size="sm">
    <b-button>Left</b-button>
    <b-button>Middle</b-button>
    <b-button>Right</b-button>
  </b-button-group>
  <br><br>
  <b-button-group size="lg">
    <b-button>Left</b-button>
    <b-button>Middle</b-button>
    <b-button>Right</b-button>
  </b-button-group>
</div>

<!-- button-group-2.vue -->
```

## Vertical variation
Make a set of buttons appear vertically stacked rather than horizontally by setting
the `vertical` prop. Split button dropdowns are not supported here.

**Example 3:** Vertical button group
```html
<div>
  <b-button-group vertical>
    <b-button>Top</b-button>
    <b-button>Middle</b-button>
    <b-button>Bottom</b-button>
  </b-button-group>
</div>

<!-- button-group-3.vue -->
```

## Dropdown menu support
Add [`<b-dropdown>`](./dropdown) menus directly inside your `<b-button-group>`. Note
that split dropdown menus are not supported when prop `vertical` is set.

**Example 4:** button group with dropdown menus
```html
<div>
  <b-button-group>
    <b-button>Button 1</b-button>
    <b-button>Button 2</b-button>
    <b-dropdown right text="Menu">
      <b-dropdown-item>Item 1</b-dropdown-item>
      <b-dropdown-item>Item 2</b-dropdown-item>
      <b-dropdown-divider></b-dropdown-divider>
      <b-dropdown-item>Item 3</b-dropdown-item>
    </b-dropdown>
    <b-button>Button 3</b-button>
    <b-dropdown right split text="Split Menu">
      <b-dropdown-item>Item 1</b-dropdown-item>
      <b-dropdown-item>Item 2</b-dropdown-item>
      <b-dropdown-divider></b-dropdown-divider>
      <b-dropdown-item>Item 3</b-dropdown-item>
    </b-dropdown>
  </b-button-group>
</div>

<!-- button-group-4.vue -->
```
