Breadcrumb is a Core Component provided by Adobe Core Components. Here you can find more information
Breadcrumb Basics:
- Navigation Start Level - Where in the hierarchy the breadcrumb component should start to walk down to the current page
Show hidden navigation items - Show pages marked as hidden in the breadcrumb (by default they will not be displayed)
Hide current page - Suppress the current page in the breadcrumb (by default it will be displayed)
Disable shadowing - If the page in the hierarchy is a redirect, the name of the redirecting page will be shown instead of the target.
