Breadcrumb

Breadcrumbs should be used as a navigational aid in your app or site. They indicate the current page’s location within a hierarchy and help the user understand where they are in relation to the rest of that hierarchy. They also afford one-click access to higher levels of that hierarchy.

Notes

The BitBreadcrumb is a Multi-API component which can accept the list of Items in 3 different ways: BitBreadcrumbItem class, a custom Generic class, and BitBreadcrumbOption component.
