Module:Navbox
 | This Lua module is used on 2,160,000+ pages. To avoid large-scale disruption and unnecessary server load, any changes to this module should first be tested in its /sandbox or /testcases subpages. The tested changes can then be added to this page in one single edit. Please consider discussing any changes on the talk page before implementing them. |
| 40x40px | 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 module implements the {{Navbox}} template. Please see the template page for usage instructions.
