Template:CatAutoTOC/doc
 | This is a documentation subpage for Template:CatAutoTOC. It may contain usage information, categories and other content that is not part of the original template page. |
 | This template is used on approximately 510,000 pages, or roughly 7510% of all pages. To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
Adds a Table of Contents (TOC) to a category page if the category's size warrants it.
The size thresholds are:
- < 100 pages = no TOC
- 100–1200 pages = {{Category TOC}}
- > 1200 pages = {{Large category TOC}}
Usage
{{CatAutoTOC}}
No parameters are needed
On category pages, {{CatAutoTOC}} can be placed wherever you want the TOC to be displayed.
On a category header template, it is best placed outside any <includeonly></includeonly> tags, so that the template is categorised as using CatAutoToc.

Bugs
This template uses the magic word {{PAGESINCATEGORY}} to count the number of pages in the category. Unfortunately, this function can return wildly erroneous results on some categories which have had many pages added and removed.
This bug is well-known, and has been documented in several places since 2010, including:
In the overwhelming majority of categories, the count is recorded accurately enough to support use of this template. However, as of 1 April 2002, there seems to be some issue with {{PAGESINCATEGORY}} falsely returning zero in some cases. This is now tracked in:
- Category:CatAutoTOC on pages where PAGESINCATEGORY returns zero (population: 0)
The category should contain only pages labelled as "empty". Purge page to update totals
