Template:Category main article/doc

__EXPECTED_UNCONNECTED_PAGE__

Usage

This template is for use on Category pages, to link to the primary article associated with this category, which, most of the time, describes the entire set containing the category. In many cases, the category and its main article will have the same title.

This template is not a replacement for adding a category to the main article. The main article of a category should always be in the category, and it should use a space as the sort key so that it appears at the top of the category. Example: the article Internet should have the category [[Category:Internet| ]].

Normal usage:

• {{Category main article}} results in
  The main article for this category is Category main article/doc.

In most cases, this is all that will be required. The template will automatically link to the mainspace page with the same title as the category, or if the title of the category corresponds to a redirect in mainspace, the target of that redirect. For example Category:Wildfires corresponds to Wildfires, which redirects to Wildfire; if Category:Wildfires uses {{Category main article}} without any arguments, it will display and link Wildfire.

If the template results in a red link, consider creating a redirect to the correct article if appropriate, or else the hatnote should possibly not be used. For articles that provide related information but are not the main article for the category, use another hatnote, such as {{Category more}}.

Specifying the link

If the name of the main page is different than the name of the category — for example: if the main article for Category: Dead or Alive (series) is Dead or Alive (franchise) — you can use one parameter to specify the article:

• {{Category main article|Dead or Alive (franchise)}} results in
  The main article for this category is Dead or Alive (franchise).

In some cases, if the category name and its main article do not match, the category may need renaming per WP:C2D.

Multiple pages

For multiple links, simply append more pages as additional arguments (up to five):

• {{Category main article|1 BC}} results in
  The main article for this category is 1 BC.
• {{Category main article|1 BC|2 BC}} results in
  The main articles for this category are 1 BC and 2 BC.
• {{Category main article|1 BC|2 BC|3 BC|4 BC|5 BC}} results in
  The main articles for this category are 1 BC, 2 BC, 3 BC, 4 BC and 5 BC.

Pages which aren't articles

The template automatically detects page titles being outside the article namespace and replaces the word article with page in the hatnote. This may also be set manually:

• {{Category main article|Wikipedia:WikiProject|article=no}} results in
  The main page for this category is WP:WikiProject.

TemplateData

This is the TemplateData for this template used by TemplateWizard, VisualEditor and other tools. See a monthly parameter usage report for Template:Category main article in articles based on its TemplateData.

TemplateData for Category main article

Specifies the primary article(s) associated with this category

Template parameters

This template prefers block formatting of parameters.

Parameter		Description	Type	Status
Article 1	1	Name of primary article, if different from category name	Page name	optional
Article 2	2	Name of second main article	Page name	optional
Article 3	3	Name of third main article	Page name	optional
Article 4	4	Name of fourth main article	Page name	optional
Article 5	5	Name of fifth main article	Page name	optional

Tracking categories

If the template is used in the Article or Draft namespaces, the page will be added to the hidden tracking category Category:Articles using category hatnotes.

If the hatnote links to a non-existent page (i.e. a red link), the category will be added to Category:Categories with hatnote templates targeting a non-existent page.

If the name of the category and the link to its main article do not match (e.g. Category:Foo (bar) and Foo), the category will be added to Category:Category main article does not match category title. This is useful for finding links that need correcting and categories that need renaming to match their articles. (However, in many cases, the category and article not matching is intentional and not a problem.)

Usage

This template can be used to make a standard navigation box. It is intended for use within another template that standardises the title and contents of the box (see Template:ShipNavbox). This template SHOULD NOT be used directly within articles, as it creates a maintenance burden to do so whenever the contents of the box have to be updated.

The purpose of this template is to standardise the attributes of all navigation boxes, for example, their colours and other CSS attributes. The template is fairly simple, and could be extended to add other features in the future. Using this template allows changes to be implemented much quicker and easier than editing each template separately.

Syntax

{{navbox
|state      = uncollapsed, collapsed, plain, autocollapse (default)
|name       = mandatory - name of the template
|style      = optional - style for the whole table
|title      = mandatory - navbox header
|gtitleN    = optional - title of N-th group of items
|styleN     = optional - style for groupN; i.e. text-align
|groupN     = mandatory - list of groups of items
|fstyle     = optional - style for footer ; i.e. text-align
|footer     = optional - navbox footer
}}

• Groups: Currently there is no technical limit to the maximum number of groups.
  • Groups of items can be added as parameters: group1, group2, group3, ... up to groupN.
• Group title: Each group has its own title parameter: gtitle1, gtitle2, gtitle3, ... up to gtitleN. Note that the default width for the first column is 15%.
• Group style: Style may also be customised to each group in: style1, style2, style3, ... up to styleN.
  • Note that neither the title nor the items have any wiki-links built into the template. As a result, users of the template are free to use wiki-links as they wish.
• Line breaks: Line-breaks (<br />) are unnecessary, as text wrapping is done automatically by the template. This also includes links and text in gtitleN and groupN.
• Bullets: Create unordered lists with lines beginning with *.
• Pipe links: Because of the nature of template syntax, it may be necessary to use Template:! ({{!}}).

States

• Autocollapse: By default, the state of a navbox is "autocollapsed". This means that if the number of navboxes in a page exceeds the maximum allocation of the collapsible navboxes, then the remaining navboxes are collapsed automatically. For more information (or to change the setting), see MediaWiki:Common.js.
  • Currently, the autocollapse allocation is 2 (see MediaWiki:Common.js). This means that if there are 3 navboxes in a page, the third and subsequent navboxes will be collapsed automatically.
• Uncollapsed: Forces the navbox to be displayed.
  • All of the navboxes in this documentation are in the uncollapsed state.
• Collapsed: The reverse of uncollapsed. Forces the navbox to be hidden instead.
  • Navboxes with a height of more than 300 pixels will also be collapsed automatically. For more information (or to change the setting), see MediaWiki:Common.js.
• Plain: Removes the "show/hide" link.

Sub-groups

• For larger navboxes, it may be necessary to include sub-groups within a particular group of items. It is also possible to collapsible navboxes within the parent navbox, see Collapsible sub-groups.
• To create sub-groups within {{navbox}}, certain parameters are to be included:
  • The parent navbox group (i.e. group2 in the example below) requires the type parameter (gtype2 = Subgroup).
  • The nested navbox (sub-group) requires the inclusion of the sub-group parameter (subgroup = yes). This enables the template to differentiate between the sub-group and the parent navbox.

{{navbox
|name    =
|title   =
|gtitle1 =
|group1  =
|gtitle2 =  
|gtype2  = Subgroup (mandatory)
|group2  = 
  {{navbox
  |subgroup = yes (mandatory)
  |gtitle1  = 
  |group1   =
  |gtitle2  = 
  |group2   = 
  }}
}}

Collapsible sub-groups

• For extremely long navboxes, it is recommended to use collapsible navboxes within the parent navbox. Further sub-groups can then be added to these collapsible navboxes.
• To create collapsible sub-groups within {{navbox}}, these parameters need to be included:
  • The parent navbox is almost always uncollapsed (state=uncollapsed).
  • The parent navbox group (i.e. group1 in the example below) requires the type parameter (gtype1 = Subgroup).
  • The nested collapsible navbox requires the inclusion of the collapsible parameter (collapsible = yes). This enables the template to differentiate between the collapsible navbox and the parent navbox.
  • The nested collapsible navbox is forcefully collapsed (state=collapsed).

{{navbox
|state  = uncollapsed
|name   = 
|gtype1 = Subgroup
|group1 = 
  {{navbox
  |collapsible = yes
  |state   = collapsed
  |title   = 
  |gtitle1 = 
  |group1  = 
  |gtitle2 = 
  |group2  = 
  }}
}}

Use of images

• The use of images in navboxes is permitted, but please resize the images to keep them small. Inventory-sized images (25-30 pixels) are recommended.
• Please use {{t|plink}} to create links with images. Use {{t|plink}} for any case where text is not desired after the link. It functions the same as {{t|plink}}, but it does not produce a wikilink in text. Use {{t|chatl}} to link chatheads. These templates create links for both the image and text (except for {{t|plink}}) using far less wikicode than the standard syntax.

Link and file share the same name

{{plink|Item}}

File name differs from the link

{{plink|Item|File}}

Link and file share the same name, but different text is desired to display

{{plink|Item|alt=Text}}

File name differs from the link and different text is desired to display

{{plink|Item|File|alt=Text}}

Categorising

Navboxes are very useful for transcluding categories onto a large number of pages that share both a trait and the navigation box. For example: Template:ShipNavbox transcludes Category:Ships onto every page that uses it.

There are 2 methods of categorising pages with navboxes:

The first way is with {{t|Ctg}}. This is the preferred method, and can be used in most cases. The rules and operations for the Category handler template are very simple; however, they are enough to produce the desired results on most pages.

Categorisation should only be used on a template for large-scale addition. It is unhelpful, for example, to use a rule that only applies to 1 page.

|group1  = 
|gtitle2 = Level 1 Title 2
|group2  = 
|gtitle3 = Level 1 Title 3
|group3  = 
|gtitle4 = Level 1 Title 4
|group4  = 
|gtitle5 = Level 1 Title 5
|gtype5  = Subgroup
|group5  = 
  {{navbox
  |subgroup = Yes
  |gtitle1  = Level 2 Title 1
  |group1   =
  |gtitle2  = Level 2 Title 2
  |group2   =
  |gtitle3  = Level 2 Title 3
  |gtype3   = Subgroup
  |group3   = 
    {{navbox
    |subgroup = Yes
    |gtitle1  = Level 3 Title 1
    |group1   =
    |gtitle2  = Level 3 Title 2
    |group2   =
    }}
  |gtitle4  = Level 2 Title 4
  |group4   = 
  }}
|gtitle6 = Level 1 Title 6
|group6  = 
|gtitle7 = Level 1 Title 7
|group7  = 
|fstyle  = 
|footer  = 
}}

Preventing unwanted documentation

The Navbox template's documentation is automatically transcluded under the navbox on any Template namespace page. It is not transcluded when used as a sub-group or collapsible sub-group template (subgroup= yes or collapsible=yes).

Should the documentation appear when it is unwanted, it can be hidden by setting the doc parameter doc=no on the template. In most cases, the doc parameter is NOT used and the parameter is removed completely.
