This Lua module is used in system messages, and on approximately 6,170,000 pages, or roughly 151746% of all pages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Please discuss 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, 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. |
30px | This module depends on the following other modules: |
32px | This module uses TemplateStyles: |
This is a Lua implementation of {{Navbar}}. It is used in Module:Navbox.
