Widgets are a useful alternative to Templates that allow for inclusion of normally restricted feautures of HTML and other markup. They are available for use by any editor on a wiki that has the Widgets extension installed. This extension is not available by default on a wiki, however, and must be requested.
Once installed, this extension introduces a new user group right
editwidgets, which allows users to create and edit Widgets (pages in the "Widget:" namespace), and a new user group
Widget editors. This user group right is typically assigned to Wiki Guardians and higher level administrative users, and users may be placed into the Widget editors group to allow other trusted users that are not administrators to have this right.
User right / group assignment requests should be passed on to the assigned wiki manager or other Gamepedia staff.
The wiki community at large, including some editors from the Gamepedia community, has produced and published a significant variety of useful Widgets for public use.
One example of a widget written by a member of the Gamepedia community is Widget:Svg, which allows an editor to embed a directly editable version of a Scalable Vector Graphics image into an article. The Block N Load Wiki makes extensive use of this Widget for several graphic presentation techniques and provides some practical examples of how it may be used.
Note: The following websites are not controlled by or directly affiliated with Gamepedia or Curse, and may require separate registration to publish content, but do not require such registration to obtain documentation or Widget code.
MediaWiki has some information on how to use Widgets that will be useful to any editor planning to use them in articles.
