Template:Container category/doc
Usage
Tag categories with {{Container category}}
to inform editors that they should not contain anything other than subcategories.
The categories will be added to Category:Container categories. If the template is transcluded on a page outside of the category namespace, the page will not be added to Category:Container categories.
Do not substitute this template.
Categories that are part of Wikipedia administration should be tagged with {{Wikipedia category}} instead.
Placing right-aligned content beside the template
Use {{Container category |right-aligned content}}
to place right-aligned content – such as {{portal}} (to provide a link or links to related portal or portals) and/or {{Commons category}} (to provide a link to the same or a similarly-named category at the Commons) – beside the template. If more than one box is included, ensure the widest one appears first, otherwise overlapping may occur.
{{Container category |{{Commons category|writers}}}}
produces:
Template:Commons category
