This template can be used on template documentation pages to ensure that any given template sandbox does not populate its main template's category(ies).

This template has two unnamed parameters, |1= and |2=. Near the bottom of a /doc page where the categories are usually placed, install this template as follows:

<includeonly>{{sandbox other||
<!-- Categories go below this line, please; interwikis go to Wikidata, thank you! -->
[[Category:(first category)]]
[[Category:(second category)]]
(more categories if needed)

}}</includeonly>
  • Usage of an empty first parameter (two pipes together, ​||​, at the end of the first line of code above) essentially means |1=(do nothing) and will not allow the sandbox page to populate the listed categories.
  • Note that the closing template braces (​}}​) are placed just before the </includeonly> tag. This is the same as |2=(category comment and categories). In "long hand" it may appear as follows:
<includeonly>{{sandbox other|1=<!-- keep sandbox out of categories -->|2=
<!-- Categories go below this line, please; interwikis go to Wikidata, thank you! -->
[[Category:(first category)]]
[[Category:(second category)]]
(more categories if needed)

}}</includeonly>
