Manual:$wgUseCategoryBrowser

Details
Enable experimental breadcrumb (or dmoz-style) category browsing. Output things like:


 * Encyclopedia → Music → Style of Music → Jazz

This feature can sometimes result in many duplicate parent categories being listed (depending on the category graph of a wiki). This is being tracked in.

This configuration parameter was removed in MediaWiki 1.38 and replaced with Extension:CategoryExplorer. See.
