Module:Navbar

This template is used on 2,450,000+ pages.
To avoid large-scale disruption and unnecessary server load, any changes should first be tested in this template's /sandbox or/testcases subpage, or in your own user space. The tested changes can then be added in one single edit to this template. Please consider discussing any 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.

This is a Lua implementation of {{navbar}}. It is used in Module:Navbox.
