Template:Collapsible templates
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 WP:Manual of Style#Scrolling lists and collapsible content and WP: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.

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.
