Template:Which/doc

__EXPECTED_UNCONNECTED_PAGE__

The {{Which}} template is a variant of {{Weasel inline}}, used to tag unsupported/unverifiable attributions that often employ problematic language better known as "weasel words." It is also closely related to the {{Who}} template, used to call attention to vague statements, such as "In some countries…" and "In some scientific publications…".

The output is the superscripted parenthetical text which?, linked to MOS:WEASEL with a tooltip that reads "The material near this tag possibly uses too vague attribution or weasel words."

Usage

This template is intended to be placed directly after the problematic article text.

Use good judgment when deciding whether greater specificity is objectively in the best interest of the article. Words like some or most are not banned and indeed, in some instances are both useful and appropriate. If greater specificity would result in a tedious laundry list of items with no real importance, then Wikipedia should remain concise, even if that entails being vague. If the reliable sources are not specific – as when they say only "In some countries…" – then it is appropriate that Wikipedia should reflect that level of ambiguity as well.

You may use any of the following formats:

{{Which|{{subst:DATE}}}}

…or…

{{Which|date={{subst:CURRENTMONTHNAME}} {{subst:CURRENTYEAR}}}}

…or…

{{Which|date=October 2026}}

Parameters

This template has three parameters, all named. One is mandatory while the other two are optional.

Parameters for Template:Which

Parameter	Description
|date=MonthName Year	A date stamp to when the template was added at that particular location on the page, consisting of the full month name and four-digit year. (required)
|reason=	Any additional information to guide other editors toward a resolution of the perceived deficiency in the text. In particular, you may wish to explicitly state exactly which words you think are unsuitable and provide a suggested form you think a satisfactory improvement might take. (optional)
|link=	Change the target of the linked text that the template produces, in the event a page that deals more directly with the specific issue in the text exists. (optional)

TemplateData

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

TemplateData for Which

For inline tagging of vague statements that are not able to cite a complete and unambiguous source where they are found in the page text

Template parameters

This template prefers inline formatting of parameters.

Template:Which invokes Module:Navbox using Lua.

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.

    |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.
