Breadcrumbs are used to show taxonomical context on pages that are many levels deep in a site’s hierarchy. Breadcrumbs show and link to parent, grandparent, and sometimes great-grandparent pages. Breadcrumbs are most appropriate on pages that:
All items must contain links, and the last item must be selected.
