Module:Region topic
MyWikiBiz, Author Your Legacy — Friday November 29, 2024
Jump to navigationJump to searchThis module contains the main code for Lua-based continent-/region-topic navboxes.
Usage
To create a customizable navbox based on this module, create a wrapper template invoking it with the parameters "data" and "name":
Template:((#invoke:Region topic|main |data = Module:DataPageName |name = Template:Param Template:))
Template:Para is necessary for correct "V•T•E" links; the parameter Template:Param allows creation of further wrapper templates. Template:Para is the page name of the data module for the region names and other options.
