Manual:Collapsible elements

jQuery.makeCollapsible

 * See also jQuery.makeCollapsible documentation for more information about how it works.

This module is in MediaWiki core by default as of MediaWiki 1.18 and higher. Add the class  to any element (div, table, list, anything) to trigger it.

For previous versions of MediaWiki, there are a few alternatives referenced below:
 * Collapsible tables: Add a simple class to make a table collapsible
 * NavFrame: A small element framework to set up a collapsible structure around any arbitrary content

Simple
Result: This text is collapsible.

Using the  and   attributes one can define a custom text for the toggle labels added by the script. When added in wikitext these could be populated by a localized message like:

With specified initial state
You can add  after   to have the content collapsed by default when you load the page.

To set the initial state as collapsed add " ", such as seen in the following table:

With specified collapsible part
You can specify which part is the collapsible content.

Result: This text is not collapsible; but the next is collapsible and hidden by default:

With custom toggle link
If you don't want the script to put the default toggle link (whether or not with a custom label) in your element, you can make one of your own. This could reside anywhere inside or outside the collapsible element. Its relationship to the collapsible element is detected by using an ID attribute with the prefix  and a corresponding class attribute with prefix   for the collapsible element and the togglelink respectively.

Result:

Toggle link Toggled text Additional toggle link

As part of an infobox
You can also use collapsible elements into infoboxes, such as seen in the example on the right.
