I'm helping to my job's internal wiki and I find subpages useful for writing pages of a tutorial related to a topic. I understand how subpages are configured, but when I was reviewing other wikis to see how subpages can be used, I found that the Spanish version of Wikibooks renders the title of the subpages separating each ancestor's title in different lines, instead of one huge title with slashes. Here is an example.How can I achieve that kind of presentation in my wiki? It can be obtained with the default installation? Is a extension needed? Or it is necessary to edit PHP files directly?
How to render MediaWiki subpages' titles like the Spanish Wikibooks?
