Editing Help/Links (section)

== Subpage feature == <!--T:288-->
</translate>
<translate><!--T:289--> MediaWiki has a [[<tvar name=1>mw:Special:MyLanguage/Help:subpages</tvar>|subpage]] feature that may or may not be active depending on the project and namespace.</translate>
<translate><!--T:290--> If it's activated, the following rules apply; otherwise, "A/b" is simply a standalone page with that name.</translate>

<translate><!--T:291--> A page's [[w:tree structure|tree structure]] is formed using forward slashes in page names: A/b is considered a subpage of A, making A the parent of A/b; additionally, A/b/c is a subpage of A/b; meanwhile, A/a, A/b, and A/c are categorized as sibling pages.</translate>

<translate><!--T:292--> The subpage body automatically displays links to all parent pages without needing specific wikitext.</translate>
<translate><!--T:293--> These links appear even if the parent page doesn't exist.</translate>
<translate><!--T:294--> However, if any ancestor page in the sequence is missing, the chain of links will stop before that point.</translate>
<translate><!--T:295--> Additionally, the capitalization of letters after the forward slash in the page name matters, meaning "<tvar name=1>/subpage</tvar>" and "<tvar name=2>/Subpage</tvar>" refer to different pages.</translate>

<translate>
<!--T:296-->
The functions, [[<tvar name=1>Special:MyLanguage/Help:What links here</tvar>|What links here]] and [[<tvar name=2>Special:MyLanguage/Help:Related changes</tvar>|Help:Related changes]] do not consider these automatically generated links.

<!--T:297-->
When the subpage feature is enabled within a namespace, any forward slash in a page's name automatically creates a subpage structure, regardless of whether it was intended or not.

<!--T:298-->
You can find a list of subpages using <tvar name=1>[[Special:PrefixIndex]]</tvar>.

=== Using variables === <!--T:299-->

<!--T:300-->
When utilizing the subpage feature within namespace A on page A:B/c/d, <tvar name=1><nowiki></nowiki></tvar> shows B/c while <tvar name=2><nowiki></nowiki></tvar> shows d.

=== Using relative links === <!--T:301-->

<!--T:302-->
Within a subpage hierarchy, you can utilize the following relative links:
</translate>

* <translate><!--T:303--> <tvar name=1><nowiki>[[../]]</nowiki></tvar> links to the parent page of the current subpage.</translate> <translate><!--T:304--> For example, on page A/b, it takes you to page A, and on page A/b/c, it directs you to page A/b.</translate>
* <translate><!--T:305--> <tvar name=1><nowiki>[[../../]]</nowiki></tvar> links to the grandparent page of the current subpage.</translate> <translate><!--T:306--> For example, on page A/b/c, it points to page A.</translate>
* <translate><!--T:307--> <tvar name=1><nowiki>[[../s]]</nowiki></tvar> links to a sibling page of the current subpage.</translate> <translate><!--T:308--> For example, on page A/b, it leads to page A/s.</translate>
* <translate><!--T:309--> <tvar name=1><nowiki>[[../../s]]</nowiki></tvar> links to an "uncle" page of the current subpage.</translate> <translate><!--T:310--> For example, on page A/b/c, it points to page A/s.</translate>
* <translate><!--T:311--> <tvar name=1><nowiki>[[/s]]</nowiki></tvar> links direct to a subpage.</translate> <translate><!--T:312--> On page A, it functions similarly to <tvar name=1><nowiki>[[A/s]]</nowiki></tvar>.</translate> <translate><!--T:313--> However, linking from a namespace with an enabled subpage feature to a main namespace page starting with <tvar name=1>"/"</tvar> requires a workaround: adding a colon before the page name.</translate>

<translate><!--T:314--> Relative links remain functional even when all pages within a hierarchy are renamed to reflect a change in the root's name, even if the root becomes a child of a new parent.</translate>
<translate><!--T:315--> Users with the appropriate permissions, such as administrators and those with the <tvar name=1><code>move-subpages</code></tvar> right, have the option to move both the main page and its subpages during a renaming process.</translate>
