|This is one of Pikmin Fanon's help pages, and it is meant to aide users by increasing their ability to positively contribute to the wiki. Additional information added to help pages such as this one is always welcome.|
Categories provide automatic indexes that help with navigation around Pikmin Fanon.
You can categorize pages and files by adding one or more Category tags to the content text. These tags create links at the bottom of the page that take you to the list of all pages in that category, which makes it easy to browse related articles.
Each of the pages in the Category namespace represents what we call a category, a grouping of related pages, and each page in the category namespace contains an index for the pages of its category. For example, this page belongs to "Category:Help". If you open the "Category:Help" page, you will see a link to this page there.
When a page belongs to one or more categories, these categories appear in a light-green box at the bottom of the page.
The category pages themselves contain 2 parts :
- The top part is optional and may contain text that can be edited, like any other page,
- The bottom part is an ever present, automatically generated, alphabetical list of all pages in that category, in the form of links.
To assign a category to a page, simply add the link "[[Category:Category name]]" to the page's wikitext. The usual place to add it is at the bottom of the page.
To link a category page within a page as a normal wiki link (without adding the page to the category), prefix the link name with a colon. For example: [[:Category:Enemies]]
New categories can be created before assigning any page to it, in the same way as any other regular page.
For a complete list of all categories which have at least one page, see Special:Categories.
For a complete list of all created/edited categories, including the ones that don't have any page, see Special:Allpages/Category: (note the colon at the end).
Adding a page to a category
To add a page or uploaded file to a category, simply edit the page and add the following text (where Name is the name of the category you want to add it to).
Any number of Category tags may be added to the page and the page will be listed in all of them. Category tags, along with interwiki language links placed in the sidebar, are usually added at the very bottom of the page for the convenience of other editors.
On a categorised page, categories are displayed in the Categories: box strictly in the order they appear in the wikitext.
By default, a page is sorted within a category under the first letter of its full name including the namespace. Also, MediaWiki groups accented characters separately from their unaccented version, so pages starting by À, Á, Ä, will be listed under separate headings, instead of under heading A.
A sort key specifies under which letter heading, and where in the category list, the page will appear. You can add a sort key by placing it inside the tag after a pipe character. For example, the tag below will add the page under heading "S".
Sort keys are case-sensitive, and spaces and other characters are also valid. The order of the sections within a category follows the Unicode sort order. The sort key does not change the page title displayed in the category.
Creating a category page
Categories exist even if their page has not been created, but these categories are isolated from others and serve little purpose for organization or navigation.
A category is created by creating a page in the Category: namespace. A category page can be created the same way as other wiki pages (see Help:Starting a new page); just add "
Category:" before the page title.
To avoid extra work, try searching within Pikmin Fanon's other categories or ask another user before creating a new category. The list of all categories can be found in "Special pages" in the "tools" box of the sidebar.
Unlike other wiki pages, it is not possible to rename (move) a category. It is necessary to create a new category and change the Category tag on every page. The new category will not have the older category's page history, which is undesirable if there are many revisions.
Managing the category hierarchy
Categories may belong to other categories in a hierarchy. Since category pages are much like any other page, a Category tag may be added to the bottom of a category page.
It is a good idea to organize all categories into a hierarchy with a single top level category. The category structure can take the form of a tree with separate branches, but more often will have a graph structure. Never create a new category page without putting it in a category of its own; there should be a contiguous chain of parent-child links between each category and the top level category.
The categories that a page is in are normally listed at the bottom of the page. A category can be hidden from this list by adding the magic word "
__HIDDENCAT__" to the category page. Hidden categories are not hidden from category pages.
Users can choose to see hidden categories in a separate "Hidden categories" list, by checking "Show hidden categories" in the "Appearance" section of Special:Preferences.

Linking to a category
To create a link to a category, use a leading colon before the category name (without this colon, the current page would be added to the category):
To change the link text, write the text inside the link tag after a pipe:
[[:Category:Help|Help category]]→ Help category
Redirect pages that redirect to categories must also use the colon, otherwise they will be added to the category instead of redirecting.
Redirecting a category
Like normal wiki pages, category pages can be redirected to other normal or category pages. However, this is not recommended, as pages categorised in redirected categories do not get categorised in the target category.
Certain syntax issues, such as a broken image link, or too many expensive parser functions, can cause a page to be added to a tracking category. See Help:Tracking categories for details.
