Help:Transclusion/en

Transclusion is a general MediaWiki term for including things into a page using double-brace " – " markup. This includes templates, pages in other namespaces, magic words, output of parser functions, some Special pages, interwiki pages, and more.

Basic use
To transclude a page, include both the namespace and the page name (separated with a colon) within the double-brace: When transcluding a template, you may omit the namespace and colon: When transcluding an article in the Main namespace, you may omit the namespace: When transcluding a subpage of the target page, you may use the subpage name by itself:

Parameters
Transcluded templates and special pages may accept parameters:

Source page syntax
Three tags (noinclude, includeonly, and onlyinclude) control which content appears in the target page.
 * noinclude
 * Content within the  tags is excluded from transclusion on the target page. This content still appears on the source page.


 * includeonly
 * Content within the  tags is transcluded on the target page, but does not appear on the source page.


 * onlyinclude
 * Content within the  tags is transcluded on the target page, and also appears on the source page.
