Extension:NiceCategoryList3/en

The NiceCategoryList3 extension displays a category listing, including sub-categories, in a number of useful formats. This is intended to allow easier navigation of a wiki's category tree. It implements a new tag,, which generates a list of all pages and sub-categories in a given category. The list can display multiple levels of sub-categories, and has several options for the display style.

This extension was originally created by Kichik as Extension:NiceCategoryList, was enhanced by JohanTheGhost and *Surak* and Crafty Coding. This was updated to work for recent version of MediaWiki by JLTRY

 * If the option, the block is a usual headings block, starting at .  {n} means a numeric value that starts at {headstart} and is increased on each subordinate level of the category list.  The default setting is  .  It can be set back to the default of previous versions by using   in LocalSettings.php.
