Button group

Angular Bootstrap 5 Button group component

Group a series of buttons together on a single line with the button group.

Basic example

Wrap a series of buttons with .btn in .btn-group.

        
            
            <div class="btn-group" role="group" aria-label="Basic example">
              <button type="button" class="btn btn-primary" mdbRipple>Left</button>
              <button type="button" class="btn btn-primary" mdbRipple>Middle</button>
              <button type="button" class="btn btn-primary" mdbRipple>Right</button>
            </div>

Ensure correct role and provide a label:
In order for assistive technologies (such as screen readers) to convey that a series of buttons is grouped, an appropriate role attribute needs to be provided. For button groups, this would be role="group", while toolbars should have a role="toolbar".
In addition, groups and toolbars should be given an explicit label, as most assistive technologies will otherwise not announce them, despite the presence of the correct role attribute. In the examples provided here, we use aria-label, but alternatives such as aria-labelledby can also be used.

These classes can also be added to links. Use the .active class to highlight a link.

Active link Link Link 
        
            
            <div class="btn-group">
              <a href="#!" class="btn btn-primary active" mdbRipple>Active link</a>
              <a href="#!" class="btn btn-primary" mdbRipple>Link</a>
              <a href="#!" class="btn btn-primary" mdbRipple>Link</a>
            </div>

Outlined styles

Use the following button styles to show the colors only for the border of the element.

        
            
            <div class="btn-group shadow-0" role="group" aria-label="Basic example">
              <button type="button" class="btn btn-outline-secondary" data-mdb-color="dark">
                Left
              </button>
              <button type="button" class="btn btn-outline-secondary" data-mdb-color="dark">
                Middle
              </button>
              <button type="button" class="btn btn-outline-secondary" data-mdb-color="dark">
                Right
              </button>
            </div>

Toolbar

Combine sets of button groups into button toolbars for more complex components. Use utility classes as needed to space out groups, buttons, and more. 

        
            
            <div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups">
              <div class="btn-group me-2" role="group" aria-label="First group">
                <button type="button" class="btn btn-primary" mdbRipple>1</button>
                <button type="button" class="btn btn-primary" mdbRipple>2</button>
                <button type="button" class="btn btn-primary" mdbRipple>3</button>
                <button type="button" class="btn btn-primary" mdbRipple>4</button>
              </div>
              <div class="btn-group me-2" role="group" aria-label="Second group">
                <button type="button" class="btn btn-primary" mdbRipple>5</button>
                <button type="button" class="btn btn-primary" mdbRipple>6</button>
                <button type="button" class="btn btn-primary" mdbRipple>7</button>
              </div>
              <div class="btn-group" role="group" aria-label="Third group">
                <button type="button" class="btn btn-primary" mdbRipple>8</button>
              </div>
            </div>

Feel free to mix input groups with button groups in your toolbars. Similar to the example above, you’ll likely need some utilities though to space things properly. 

        
            
            <div class="btn-toolbar mb-3" role="toolbar" aria-label="Toolbar with button groups">
              <div class="btn-group me-2" role="group" aria-label="First group">
                <button type="button" class="btn btn-primary" mdbRipple>1</button>
                <button type="button" class="btn btn-primary" mdbRipple>2</button>
                <button type="button" class="btn btn-primary" mdbRipple>3</button>
                <button type="button" class="btn btn-primary" mdbRipple>4</button>
              </div>
              <div class="input-group">
                <div class="input-group-text" id="btnGroupAddon">@</div>
                <input
                  type="text"
                  class="form-control"
                  placeholder="Input group example"
                  aria-label="Input group example"
                  aria-describedby="btnGroupAddon"
                />
              </div>
            </div>
            <div
              class="btn-toolbar justify-content-between"
              role="toolbar"
              aria-label="Toolbar with button groups"
            >
              <div class="btn-group" role="group" aria-label="First group">
                <button type="button" class="btn btn-primary" mdbRipple>1</button>
                <button type="button" class="btn btn-primary" mdbRipple>2</button>
                <button type="button" class="btn btn-primary" mdbRipple>3</button>
                <button type="button" class="btn btn-primary" mdbRipple>4</button>
              </div>
              <div class="input-group">
                <div class="input-group-text" id="btnGroupAddon2">@</div>
                <input
                  type="text"
                  class="form-control"
                  placeholder="Input group example"
                  aria-label="Input group example"
                  aria-describedby="btnGroupAddon2"
                />
              </div>
            </div>

Sizing

Instead of applying button sizing classes to every button in a group, just add .btn-group-* to each .btn-group, including each one when nesting multiple groups. 





        
            
            <!-- Large -->
            <div class="btn-group btn-group-lg" role="group" aria-label="Basic example">
              <button type="button" class="btn btn-primary" mdbRipple>Left</button>
              <button type="button" class="btn btn-primary" mdbRipple>Middle</button>
              <button type="button" class="btn btn-primary" mdbRipple>Right</button>
            </div>
            <!-- Standard -->
            <div class="btn-group" role="group" aria-label="Basic example">
              <button type="button" class="btn btn-primary" mdbRipple>Left</button>
              <button type="button" class="btn btn-primary" mdbRipple>Middle</button>
              <button type="button" class="btn btn-primary" mdbRipple>Right</button>
            </div>
            <!-- Small -->
            <div class="btn-group btn-group-sm" role="group" aria-label="Basic example">
              <button type="button" class="btn btn-primary" mdbRipple>Left</button>
              <button type="button" class="btn btn-primary" mdbRipple>Middle</button>
              <button type="button" class="btn btn-primary" mdbRipple>Right</button>
            </div>

Vertical variation

Use the following code to group a series of buttons in a vertical button group.

        
            
              <div class="btn-group-vertical" role="group" aria-label="Vertical button group">
                <button type="button" class="btn btn-primary" mdbRipple>Button</button>
                <button type="button" class="btn btn-primary" mdbRipple>Button</button>
                <button type="button" class="btn btn-primary" mdbRipple>Button</button>
                <button type="button" class="btn btn-primary" mdbRipple>Button</button>
                <button type="button" class="btn btn-primary" mdbRipple>Button</button>
                <button type="button" class="btn btn-primary" mdbRipple>Button</button>
              </div>

Colors

Choose from several predefined button styles, each serving its own semantic purpose, with a few extras thrown in for more control.















        
            
            <div class="btn-group shadow-0" role="group">
              <button type="button" class="btn btn-light" data-mdb-color="dark" mdbRipple>Left</button>
              <button type="button" class="btn btn-light" data-mdb-color="dark" mdbRipple>Middle</button>
              <button type="button" class="btn btn-light" data-mdb-color="dark" mdbRipple>Right</button>
            </div>
            <div class="btn-group shadow-0" role="group">
              <button type="button" class="btn btn-link" data-mdb-color="dark" mdbRipple>Left</button>
              <button type="button" class="btn btn-link" data-mdb-color="dark" mdbRipple>Middle</button>

Button Group - API

Import

        
            
      import { MdbRippleModule } from 'mdb-angular-ui-kit/ripple';
        …
        @NgModule ({
          ...
          imports: [MdbRippleModule],
          ...
        })

CSS variables

As part of MDB’s evolving CSS variables approach, Button group now use local CSS variables for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.

Most of variables for .btn-group are the same as for buttons.

        
            
        // .btn-group,
        // .btn-group-vertical
        --#{$prefix}btn-box-shadow: #{$btn-box-shadow};
        --#{$prefix}btn-hover-box-shadow: #{$btn-hover-box-shadow};
        --#{$prefix}btn-focus-box-shadow: #{$btn-focus-box-shadow};
        --#{$prefix}btn-active-box-shadow: #{$btn-active-box-shadow};
        --#{$prefix}btn-group-transition: #{$btn-group-transition};

        // .btn-group,
        // .btn-group-lg > .btn,
        // .btn-group-sm > .btn
        --#{$prefix}btn-border-radius: #{$btn-border-radius};

SCSS variables

        
            
        $btn-group-border-radius: calc(4px - 1px);
        $btn-group-transition: color 0.15s ease-in-out, background-color 0.15s ease-in-out, border-color 0.15s ease-in-out, box-shadow 0.15s ease-in-out;
