If this is required for a category where items are manually added rather than added by a template, then the option
notemplate can be used to exclude the text "added by a template".
This template is also used on Category:Hidden categories itself, in which case it does not mark that category as hidden (otherwise a category loop would be created).
|The above documentation is transcluded from Template:Maintenance category/doc. (edit | history)|
Editors can experiment in this template's sandbox (create | mirror) and testcases (create) pages.
Please add categories to the /doc subpage. Subpages of this template.
