Module:Team roster navbox/sandbox

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

This module is used to implement {{Team roster navbox}}, a helper template used to implement the individual team roster navboxes for the Major League Baseball teams.

At present, it parses any list<number> arguments to the template and replaces spaces in each list item with &nbsp; in order to prevent wrapping. It then calls Module:Navbox._navbox() to create the navbox. (Note the preprocessing done by Module::Navbox.navbox() has not been copied to this module and so is skipped.)

The above documentation is transcluded from Module:Team roster navbox/doc. (edit | history)
Editors can experiment in this module's sandbox (edit | diff) and testcases (create) pages.
