The breadcrumb is a secondary navigation pattern that helps a user understand the hierarchy among levels and navigate back through them.
Breadcrumbs show users their current location relative to the information architecture and enable them to quickly move up to a parent level or previous step.
Page link(1): Directs users to the parent-level page.
Separator(2): Clearly distinguishes between each page.
By default, breadcrumb trails should not include the current page. If a page doesn’t have a title or the current page is not clear, it can be included in the breadcrumb trail. If the current page is included in a breadcrumb trail, it is always the last text listed and is not an interactive link.
