Bootstrap Vue Breadcrumb Component

Example #

The breadcrumb navigation provides links back to each previous page the user navigated through and shows the current location in a website or an application. You don’t have to add separators, because they automatically added in CSS through ::before and content.

<CBreadcrumb>
  <CBreadcrumbItem active>Home</CBreadcrumbItem>
</CBreadcrumb>
<CBreadcrumb>
  <CBreadcrumbItem href="#">Home</CBreadcrumbItem>
  <CBreadcrumbItem active>Library</CBreadcrumbItem>
</CBreadcrumb>
<CBreadcrumb>
  <CBreadcrumbItem href="#">Home</CBreadcrumbItem>
  <CBreadcrumbItem href="#">Library</CBreadcrumbItem>
  <CBreadcrumbItem active>Data</CBreadcrumbItem>
</CBreadcrumb>

Dividers #

Dividers are automatically added in CSS through ::beforeopen in new window and contentopen in new window. They can be changed by modifying a local CSS custom property --coreui-breadcrumb-divider, or through the $breadcrumb-divider Sass variable — and $breadcrumb-divider-flipped for its RTL counterpart, if needed. We default to our Sass variable, which is set as a fallback to the custom property. This way, you get a global divider that you can override without recompiling CSS at any time.

<CBreadcrumb style="--cui-breadcrumb-divider: '>'">
  <CBreadcrumbItem href="#">Home</CBreadcrumbItem>
  <CBreadcrumbItem active>Library</CBreadcrumbItem>
</CBreadcrumb>

When modifying via Sass, the quoteopen in new window function is required to generate the quotes around a string. For example, using > as the divider, you can use this:

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

It's also possible to use an embedded SVG icon. Apply it via our CSS custom property, or use the Sass variable.

<CBreadcrumb style="--cui-breadcrumb-divider: url(&#34;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&#34;);">
  <CBreadcrumbItem href="#">Home</CBreadcrumbItem>
  <CBreadcrumbItem active>Library</CBreadcrumbItem>
</CBreadcrumb>

$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");

You can also remove the divider setting --cui-breadcrumb-divider: ''; (empty strings in CSS custom properties counts as a value), or setting the Sass variable to $breadcrumb-divider: none;.

<CBreadcrumb style="--cui-breadcrumb-divider: '';">
  <CBreadcrumbItem href="#">Home</CBreadcrumbItem>
  <CBreadcrumbItem active>Library</CBreadcrumbItem>
</CBreadcrumb>

$breadcrumb-divider: none;

Accessibility #

Since breadcrumbs provide navigation, it's useful to add a significant label such as aria-label="breadcrumb" to explain the type of navigation implemented in the <nav> element. You should also add an aria-current="page" to the last item of the set to show that it represents the current page. Bootstrap Vue automatically add all of this labels to breadcrumb's components.
