Module:Region topic
 | This module is rated as alpha. It is ready for third-party input, and may be used on a few pages to see if problems arise, but should be watched. Suggestions for new features or changes in their input and output mechanisms are welcome. |
This module contains the main code for Lua-based continent-/region-topic navboxes.
Usage
[edit]To create a customizable navbox based on this module, create a wrapper template invoking it with the parameters "data" and "name":
{{#invoke:Region topic|main
|data = Module:DataPageName
|name = {{{name|{{subst:PAGENAME}}}}}
}}
|name= is necessary for correct "V•T•E" links; the parameter {{{name}}} allows creation of further wrapper templates. |data= is the page name of the data module for the region names and other options.
