 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.

 If your control element is targeting a single collapsible element – i.e. the `data-target` attribute is pointing to an `id` selector – you should add the `aria-controls` attribute to the control element, containing the `id` of the collapsible element. Modern screen readers and similar assistive technologies make use of this attribute to provide users with additional shortcuts to navigate directly to the collapsible element itself.

 If you're using navs to provide a navigation bar, be sure to add a `role="navigation"` to the most logical parent container of the `<ul>`, or wrap a `<nav>` element around the whole navigation. Do not add the role to the `<ul>` itself, as this would prevent it from being announced as an actual list by assistive technologies.
 
-Note that navigation bars, even if visually styled as tabs with the `.nav-tabs` class, should **not** be given `role="tablist"`, `role="tab"` or `role="tabpanel"` attributes.

 {{< callout danger >}}
 Note that the tab JavaScript plugin **does not** support tabbed interfaces that contain dropdown menus, as these cause both usability and accessibility issues. From a usability perspective, the fact that the currently displayed tab's trigger element is not immediately visible (as it's inside the closed dropdown menu) can cause confusion. From an accessibility point of view, there is currently no sensible way to map this sort of construct to a standard WAI ARIA pattern, meaning that it cannot be easily made understandable to users of assistive technologies.
