The built - in logic for the virtual nodes works for content items, however when filtering, the details view control does not have a mechanism with which to know on what is being filtered, so that the breadcrumb can add proper titles and build the links correctly.
If you want to try to achieve the desired functionality when using classifications to filter the content, you might need to override the IBreadcrumExtender.GetVirtualNodes
method which is implemented by ContentView
. However you might need to create logic which can help you taxonomy title from the item which is being filtered.
