Module:Infobox

Module documentation[view] [edit] [history] [purge]

This module implements a metatemplate, and may be invoked by templates using its corresponding template Template:Infobox, or used directly from other modules.

Module:Infobox is a module that implements the {{Infobox}} template. Infobox templates can be made by using the template or by calling the _sidebar function from another module.

On templates, you can create an infobox by using {{Infobox}}, which calls this module's wrapper function.

On modules, you can include local infobox= require("Module:Infobox")._infobox to create an infobox.
