Subpages introduce some hierarchical organization into wiki pages, with levels of the hierarchy separated by slashes (/).

Where it works[edit | edit source]

By default, MediaWiki's subpage feature is turned off in the main namespace, but can be used on talk pages and 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[edit | edit source]

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

  • 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 previous pages will automatically appear at the top. These links do not appear, however, if the previous pages have not yet been created.

Subpages/subpage[edit | edit source]

This is an example of a subpage of Help:Subpages.

  • Help:Subpages – parent page
  • Help:Subpages/subpage – this page
  • Help:Subpages/subpage/sub-subpage – child page

When the parent page actually exists, a link to the parent page automatically appears under the page name header at the top unless the subpage feature is turned off.

Subpages/subpage/sub-subpage[edit | edit source]

This is an example of a sub-subpage of Help:Subpage.

  • Help:Subpages|Help:Subpages – grandparent page
  • Help:Subpages/subpage|Help:Subpages/subpage – parent page
  • Help:Subpages/subpage/sub-subpage – this page

When the antecedent pages actually exist, the links to antecedent pages automatically appear under the page name header at the top, creating a breadcrumb, unless the subpage feature is turned off.

There are various uses for the subpage feature. Some of the typical usages of subpages are:

  • to create archives of old discussions under a talk page
  • to create scratchpad editing spaces under a user page
  • to create other language versions of a document in multilingual wikis

Subpages are useful for organizing 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 category feature, which is more suitable for creating a hierarchical network of information.

Tools.png Tip for wiki admins: You can specify the namespaces to have the subpage feature enabled with $wgNamespacesWithSubpages array.
