Template:One source

Template documentation follows
Note: the template above may sometimes be partially or fully invisible.
Visit "Template:One source/doc" to edit its documentation if it is available. (How does this work?)

Purpose

This template alerts readers to encyclopedic content that appears to rely on a single source.

A single source is usually less than ideal because it may be inaccurate or biased. Without other sources for corroboration, accuracy or neutrality may be suspect. Finding multiple independent sources improves the encyclopedia's reliability. For BLP articles that cite one source and need more, use {{BLP one source}} instead.

Citing only one source is not a policy violation. Consider not adding this tag to stubs, articles being actively expanded, or articles with no apparent verifiability or neutrality problems.

This tag is more specific than the widely used {{More citations needed}} and {{More footnotes needed}} templates. Prefer it when an article needs both additional inline citations and more than one source.

Usage

{{One source|date=October 2026}} {{One source|section|date=October 2026}} {{One source|text=Alternate first sentence|date=October 2026}} {{One source|section|find=topic search keywords|date=October 2026}}

Parameters

Subject

The first unnamed parameter replaces "This article relies" with "This PARAMETER relies". For example, {{One source|section}} displays:

Text

You can replace the entire first sentence with the text= parameter when the standard wording does not apply but the general intent does.

Date

As with most cleanup templates, the |date= parameter sorts the article into subcategories of Category:Articles lacking sources, allowing the oldest problems to be addressed first. You do not need to specify the date manually; a bot will add it automatically.

Find parameters

Two 'find' parameters control the {{find sources}} links optionally shown by the template. By default, the template displays {{find sources}} with a quoted query equal to the exact article title. For long descriptive titles or parenthetical disambiguation terms, this may not give useful results. Use:

• |find= for an exact (double-quoted) search; corresponds to {{find sources}} positional param |1=.
• |find2= for an unquoted search; corresponds to {{find sources}} param |2=. The alias |unquoted= may be used instead.

The second param is especially useful with the 'section' version. Try |find=Article title​|find2=Section title}} for improved results.

Passing |find=none suppresses the find sources links. (Specifying |find=none together with a nonempty |find2= is not valid.)

Editorial usage

Use this template only for encyclopedic content that has a verified, cited source—but only one.

A single source is not automatically a problem. Use good judgment and common sense.

Consider improving the article or attempting in good faith to find additional citations before adding this template.

It is good form to provide a rationale in your edit summary or on the article's talk page. The more specifically you describe your concerns, the less likely others are to misunderstand.

If you believe problems exist beyond the sources themselves, address them with an appropriate template (see below) rather than simply questioning the sources.

Alternatives

• Inline version
  • {{Single Source-inline}} – same concept within individual sentences or phrases.
• Sources and citations
  • {{Failed verification}} – Citation does not support the article's claim(s)
• Article content
  • {{POV}} – Neutrality, point-of-view, bias

Administrivia

This template categorises tagged articles into Category:Articles needing additional references. If a date is supplied, a monthly category like Category:Articles needing additional references from October 2026 is used instead.

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.

  |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.
