{{hidden archive bottom}}

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}}.

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

Note: {{Collapse}} needs to be substed in order for the time stamp functionality to work properly.

{{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.

HTML version

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

A workaround for this is the "pure HTML" (<table>, etc.) variant of this template, {{Collapse/HTML}}, which is identical (same parameters, etc.) other than in not using wikimarkup for the layout-table code.

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 having rules for the three classes (collapsible, uncollapsed, and collapsed) in the appropriate CSS files, and some related JavaScript installed. This template transcludes {{main other}} and {{lorem ipsum}}, which should also be imported at the same time.

For MediaWiki versions ≥ 1.18, this template can simply be exported and then imported into another MediaWiki installation. 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.
