Editing Help:Subpages

{{PD Help Page}}
'''Subpages''' introduce some hierarchical organization into wiki pages, with levels of the hierarchy separated by slashes (<code>/</code>).

=== Where it works ===
By default, MediaWiki's subpage feature is turned off in the main namespace, but can be used on [[Help:Talk pages|talk pages]] and [[Help:User page|user pages]]. See [[Help:Namespaces]]. In namespaces where the feature is switched off, any slashes (/) within a page name are simply part of the page name and do nothing special.

=== How it works ===
Slashes (/) within a page name break the page into parent and subpages, recursively, e.g.:

* [[Help:Subpages]] - this page
* [[Help:Subpages/subpage]] - child page
* [[Help:Subpages/subpage/sub-subpage]] - grandchild page

Note that the part of page names after a slash is case sensitive including the first letter.

In subpages, a link back to antecedent pages will automatically appear at the top. These links do not appear, however, if the antecedent pages have not yet been created.

=== Use of subpages ===
There are various uses for the subpage feature. Some of the typical usages of subpages are:
* to create archives of old discussions under a [[Help:Talk pages|talk page]]
* to create scratchpad editing spaces under a [[Help:User page|user page]]
* to create other language versions of a document in multilingual wikis

Subpages are useful for organising information hierarchically. On the other hand, subpages tend to have a long name that is hard to remember, so it may be more user-friendly to use them as little as possible. You can also organize pages with the [[Help:Category|category]] feature, which is more suitable for creating a hierarchical network of information. 

{{Admin tip|tip=You can specify the namespaces to have the subpage feature enabled with {{mediawiki|Manual:$wgNamespacesWithSubpages|$wgNamespacesWithSubpages}} array.}}
