Template:Set index article/doc

This is a documentation subpage for Template:Set index article.
It may contain usage information, categories and other content that is not part of the original template page.

This template is used on approximately 6,400 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.

This is the {{Set index article}} template.

It can be used without any parameters to mark a page as a generic set index article. Like this:

{{Set index article}}

Which renders like this:

This set index article includes a list of related items that share the same name (or similar names).
If an internal link incorrectly led you here, you may wish to change the link to point directly to the intended article.

It then categorises the page into Category:Set index articles.

Parameters

Type

This template can also be fed a name of a type of set index article. For instance like this:

{{Set index article|comics}}

And it will then categorise the page into Category:Set index articles on comics, but no change is made to the template's appearance on-page, which is still:

This set index article includes a list of related items that share the same name (or similar names).
If an internal link incorrectly led you here, you may wish to change the link to point directly to the intended article.

or if no type is given (note the double pipe):

{{Set index article||(sort key)}}

Defaults to first letter of article title.

Technical details

If the page name starts with "List" it does not show the "If an internal link led you here" sentence, since such pages are not likely to be unintentionally linked to.

This template only categorises a page if the page is in the main (article) space. Thus it will not categorise for instance a talk page or this template page where it might be shown or discussed.

Error handling

If there are issues with the parameters used in this template, the page will be put into either the Category:Wikipedia disambig or set index box parameter needs fixing or the Category:Unsynchronized disambiguation talk pages category.
