GuMaxDD is the drop-down menu version of the GuMax skin, initially written by Paul Y. Gu in 2007. According to him, "this design is dedicated to maximize the space for the main content page, and make wiki as a professional web site which can be applied to many types of business that suits your needs". Like many other skins from the era, it is derived from the MonoBook skin, which was MediaWiki's default skin until 2010 when it was replaced by Vector.


  • A horizontal navigation menu at the top, using dropdowns
  • A built-in article picture


  • Download and place the file(s) in a directory called GuMaxDD in your skins/ folder.
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadSkin( 'GuMaxDD' );
  •   Done - Navigate to Special:Version on your wiki to verify that the skin is successfully installed.

Changes in version 1.6


Version 1.6, released on 18 December 2020, includes a lot of bug fixes and tweaks, such as:

  • i18n
  • consistent IDs/classes (for eventual compatibility with things like VisualEditor etc.)
  • general modernization
  • Extension:Echo support
  • no-JS support — the navigation menus now work even if the user has disabled JavaScript in their browser
