This Lua module is used on 52,000+ pages and changes may be widely noticed. Test changes in the module's /sandbox or /testcases subpages, or in your own module sandbox. Consider discussing changes on the talk page before implementing them. |
This module is subject to page protection. It is a highly visible module in use by a very large number of pages, and/or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
This module implements {{collapsible list}}. Please see the template page for documentation.
