Template:Collapse/doc

__EXPECTED_UNCONNECTED_PAGE__

The {{collapse|folding text}} template is used for placing collapse boxes around short discussions and bits of discussions. To fold long discussion threads, use {{Collapse top}}... lots of text ...{{Collapse bottom}}. There are cases where these templates will not work. See Help:Collapsing for other options.

This template should only be used in accordance with the Wikipedia:refactoring talk pages guideline; it should never be used to end a discussion over the objections of other editors, except in cases of unambiguous disruptive editing.

Do not hide content in articles. This violates the Wikipedia:Manual of Style § Scrolling lists and collapsible content and Wikipedia:Manual of Style/Accessibility guidelines.

Usage

{{Collapse|1=Discussion text to be put into box.|2=Optional custom heading}}

It is definitely safest to use the named |1= and |2= parameters, because otherwise any "=" character will break the template.

For compatibility with various discussion-boxing and -closing, and discussion-wrapping templates, |1= can also be given as |content= or |text=, and |2= can also be given as |title=, |reason=, |header=, |heading=, or |result=.

This works with collapsed bulleted list (the first bullet will look correct):
{{Collapse|title=|Bulleted list}} Start bulleted list on a new line.

HTML version

If you find that the template does not function properly in a particular circumstance, this is most likely because the wikitext table markup ({|, etc.) only works when it is at the beginning of a new line.

A workaround for this is to use the "pure HTML" variant of this template, {{Collapse/HTML}}, which supports the same parameters but utilizes <table> tags in lieu of wiki markup for the table layout.

The bg parameter

The bg parameter is optional. It changes the background color. Use Web color values (e.g. #F0F2F5).

Example

{{Collapse|1=Discussion text to be put into box.|bg=#F0F2F5}} creates:

Extended content

Discussion text to be put into box.

The padding parameter

The padding parameter adjusts the amount of cell padding (defaults to 8px):

{{Collapse|1=Discussion text to be put into box.|padding=20px}} creates the following (expand the box to see the border padding effect):

Extended content

Discussion text to be put into box.

The float parameter

The float parameter allows the collapsed content to float to the left, right, or center of the page (defaults to none with width = 100%):

{{Collapse|1=Discussion text to be put into box.|float=center}} creates the following:

Extended content

Discussion text to be put into box.

{{Collapse|1=Discussion text to be put into box.|float=center|width=30em}} creates the following:

Extended content

Discussion text to be put into box.

{{Collapse|1=Discussion text to be put into box.|float=left|width=30em}} creates the following:

Extended content

Discussion text to be put into box.

{{Collapse|1=Discussion text to be put into box.|float=right|width=30em}} creates the following:

Extended content

Discussion text to be put into box.

{{Collapse|1=Discussion text to be put into box.|float=none|width=30em}} creates the following:

Extended content

Discussion text to be put into box.

Around header text

When used with a section of text, include the section header in the collapsed portion of text. For example, given:

== Heading == Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.

Replace with:

{{subst:Collapse|1= Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.|2=Heading}}

The expand parameter

Simply add |expand=yes to have the box show up in expanded form with a "hide" link, instead of collapsed form with a "show" link. Other options: |expand= yes, y, expand, expanded, uncollapse, uncollapsed. Note: |expand=no will fold the box (default).

The clear parameter

In some situations you may not want the default clear: both; CSS to apply, which puts the collapse box below any left- or right-floated content within the same HTML block. In this case, you can use |clear=none, |clear=right, or |clear=left, as needed.

When content includes tables

This template frequently breaks when used around content that consists of or includes wikitables. Such content can be made collapsible by using the {{collapse top}} and {{collapse bottom}} templates instead of {{collapse}}.

If you want to collapse only the table and not other content, you can do this using wikitable parameters. See the Collapsing tables guide for help.

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

TemplateData for Collapse

Re-using at other wikis

This template depends upon using the three classes mw-collapsible, mw-uncollapsed and mw-collapsed, which are part of MediaWiki versions ≥ 1.18. For wikis using these version of MediaWiki, this template can simply be exported and then imported into another MediaWiki installation. This template transcludes {{main other}} and {{lorem ipsum}}, which should also be imported at the same time. Some changes to the source code will need to be made in order for this template to become usable on the Main/Article (ns:0) namespace.

The toggle text can be edited at external Wiki's MediaWiki:Collapsible-expand and MediaWiki:Collapsible-collapse pages. Further information at jquery.makeCollapsible module.

Template:Collapse 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.

    {{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.
