{{Collapsible templates}}

The {{tlx|collapse|<nowiki>folding text</nowiki>}} template is used for placing collapse boxes around ''short'' discussions and bits of discussions. To fold ''long'' discussion threads, use {{tlx|Collapse top}}<code>... lots of text ...</code>{{tlx|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 {{section link|Wikipedia:Manual of Style|Scrolling lists and collapsible content}} and [[Wikipedia:Manual of Style/Accessibility]] guidelines.

== Usage ==
{{Tlx|Collapse|1&#61;<var>Discussion text to be put into box.</var>|2&#61;<var>Optional custom heading</var>}}

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

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

This works with collapsed bulleted list (the first bullet will look correct):<br>
{{Tlx|Collapse|title&#61;|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 (<code><nowiki>{|</nowiki></code>, 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, '''{{tlx|Collapse/HTML}}''', which supports the same parameters but utilizes {{tag|table|o}} tags in lieu of wiki markup for the table layout.

=== The <code>bg</code> parameter ===
The <code>bg</code> parameter is optional. It changes the background color. Use [[Web color]] values (e.g. <code>#F0F2F5</code>).

;Example:
 
<code>{<nowiki />{Collapse|1=<var>Discussion text to be put into box.</var>|bg=#F0F2F5}<nowiki />}</code> creates:

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

=== The <code>padding</code> parameter ===
The <code>padding</code> parameter adjusts the amount of cell padding (defaults to <code>8px</code>):

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

{{Collapse|1=Discussion text to be put into box.|padding=20px}}

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

<code><nowiki>{{</nowiki>Collapse|1=<var>Discussion text to be put into box.</var>|float=center<nowiki>}}</nowiki></code> creates the following:

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

<code><nowiki>{{</nowiki>Collapse|1=<var>Discussion text to be put into box.</var>|float=center|width=30em<nowiki>}}</nowiki></code> creates the following:

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

<code><nowiki>{{</nowiki>Collapse|1=<var>Discussion text to be put into box.</var>|float=left|width=30em<nowiki>}}</nowiki></code> creates the following:

{{Collapse|1=Discussion text to be put into box.|float=left|width=30em}}
{{clear}}
<code><nowiki>{{</nowiki>Collapse|1=<var>Discussion text to be put into box.</var>|float=right|width=30em<nowiki>}}</nowiki></code> creates the following:

{{Collapse|1=Discussion text to be put into box.|float=right|width=30em}}
{{clear}}
<code><nowiki>{{</nowiki>Collapse|1=<var>Discussion text to be put into box.</var>|float=none|width=30em<nowiki>}}</nowiki></code> creates the following:

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

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

{| style="background-color: lavender;color:inherit;"
| Example text|&#x3d;&#x3d; [[Help:Section|Heading]] &#x3d;&#x3d;<br />{{Lorem ipsum}}
|}

Replace with:

{{mono|{{Tlsp|Collapse|1&#61;{{Lorem ipsum}}|2&#61;[[Help:Section|Heading]]}}}}

===The <code>expand</code> parameter===
Simply add {{para|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: {{para|expand|}} <code>yes, y, expand, expanded, uncollapse, uncollapsed</code>. Note: {{para|expand|no}} will fold the box (default).

===The <code>clear</code> parameter===
In some situations you may not want the default <code>clear: both;</code> 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 {{para|clear|none}}, {{para|clear|right}}, or {{para|clear|left}}, as needed.

===When content includes tables===
This template frequently breaks when used around content that consists of or includes [[Help:Table|wikitables]]. Such content can be made collapsible by using the {{tlx|collapse top}} and {{tlx|collapse bottom}} templates instead of {{tlx|collapse}}. 

If you want to collapse only the table and not other content, you can do this using wikitable parameters. See the [[Help:Collapsing#Collapsing tables by default|Collapsing tables]] guide for help.

== Re-using at other wikis ==
This template depends upon using the three classes <code>mw-collapsible</code>, <code>mw-uncollapsed</code> and <code>mw-collapsed</code>, 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 {{tl|main other}} and {{tl|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) [[mw:Help:Namespaces|namespace]].

The toggle text can be edited at external Wiki's [[MediaWiki:Collapsible-expand]] and [[MediaWiki:Collapsible-collapse]] pages. Further information at [[mw:ResourceLoader/Modules#jquery.makeCollapsible|jquery.makeCollapsible module]].
