Breadcrumb Component
The Core Component Breadcrumb Component is a navigation component that builds a breadcrumb of links based on the page's location in the content hierarchy.
Usage
The Breadcrumb Component displays the position of the current page within the site hierarchy, allowing page visitors to navigate the page hierarchy from their current location. This is often integrated into page headers or footers.
Available options, such as the default navigation level and the ability to show the current page or hidden pages, can be defined by the template author in the
design dialog
. The content editor can then choose if hidden pages should be shown or not and the actual navigation level for the component in the
edit dialog
.
