Multi-column sorted categories
Language(s): PHP
Compatible with: MediaWiki 1.27 (or earlier)+ (all)

Instead of an unreadable old-style, concatenated, unsorted, long list of categories you can now choose to display your page categories as a modern, multi-column, sorted table.

A really nice and readable layout for MediaWiki page categories. Very easy to implement.

Simple PHP patchEdit

Patch valid for MediaWiki 1.27, or earlier. You only have to change 5 lines of code.
