Breadcrumbs

Angular Bootstrap 5 Breadcrumbs

Indicate the current page’s location within a navigational hierarchy that automatically adds separators via CSS.

Basic example

        
            
            <nav aria-label="breadcrumb">
              <ol class="breadcrumb">
                <li class="breadcrumb-item active" aria-current="page">Home</li>
              </ol>
            </nav>

            <nav aria-label="breadcrumb">
              <ol class="breadcrumb">
                <li class="breadcrumb-item"><a href="#">Home</a></li>
                <li class="breadcrumb-item active" aria-current="page">Library</li>
              </ol>
            </nav>

            <nav aria-label="breadcrumb">
              <ol class="breadcrumb">
                <li class="breadcrumb-item"><a href="#">Home</a></li>
                <li class="breadcrumb-item"><a href="#">Library</a></li>
                <li class="breadcrumb-item active" aria-current="page">Data</li>
              </ol>
            </nav>
          
        
    

Breadcrumb in navbar

Very often breadcrumb is placed in the navbar.

        
            
            <nav class="navbar navbar-expand-lg navbar-light bg-light">
              <div class="container-fluid">
                <nav aria-label="breadcrumb">
                  <ol class="breadcrumb">
                    <li class="breadcrumb-item"><a href="#">Home</a></li>
                    <li class="breadcrumb-item"><a href="#">Library</a></li>
                    <li class="breadcrumb-item active" aria-current="page"><a href="#">Data</a></li>
                  </ol>
                </nav>
              </div>
            </nav>
          
        
    

Changing the separator

Separators are automatically added in CSS through ::before and content. They can be changed by changing $breadcrumb-divider. The quote function is needed to generate the quotes around a string, so if you want > as separator, you can use this:

        
            
            $breadcrumb-divider: quote(">");
          
        
    

It’s also possible to use an embedded SVG icon:

        
            
            $breadcrumb-divider: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg'
            width='8' height='8'%3E%3Cpath d='M2.5 0L1 1.5 3.5 4 1 6.5 2.5 8l4-4-4-4z'
            fill='currentColor'/%3E%3C/svg%3E");
          
        
    

The separator can be removed by setting $breadcrumb-divider to none:

        
            
            $breadcrumb-divider: none;
          
        
    

Accessibility

Since breadcrumbs provide a navigation, it’s a good idea to add a meaningful label such as aria-label="breadcrumb" to describe the type of navigation provided in the <nav> element, as well as applying an aria-current="page" to the last item of the set to indicate that it represents the current page.
