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
.

Edit Dialog
The edit dialog allows the content author to suppress hidden and active pages in the breadcrumbs as well as the depth in the hierarchy it should display.
- Navigation Start Level - Where in the hierarchy the breadcrumb component should start to walk down to the current page. For example:
- 0 starts at /content
- 1 starts at /content/<yourSite>
- 2 starts at /content/<yourSite>/<country>
- 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. See the Shadow Site Structure Support of the Navigation Component for more information.
- ID - This option allows to control the unique identifier of the component in the HTML and in the Data Layer .
- If left blank, a unique ID is automatically generated for you and can be found by inspecting the resulting page.
- If an ID is specified, it is the responsibility of the author to make sure that it is unique.
- Changing the ID can have an impact on CSS, JS and Data Layer tracking.
