Editing Help:Collapsing tables and more (section)

==Collapsible tables==
The <code>[[mw:Manual:Collapsible elements|mw-collapsible]]</code> class can make any element collapsible, but tables are particularly simple to make collapsible. Adding the <code>mw-collapsible</code> class to a table automatically positions the toggle, and selects which parts to collapse. 

A common use is to make a collapsible layout table, which always displays an introduction or summary, but hides the rest of the content from immediate view. The introduction or summary is in the first row, and the content is in subsequent rows. The content is then easily accessible by using the 'show' button.

In the examples below, the use of the class <code>wikitable</code> is merely for appearance; it is not needed for <code>mw-collapsible</code> to function.

{| class=wikitable style="width:80%;"
!Code entered!!Output produced
|-
|style="width:50%;"|
<syntaxhighlight lang="wikitext">{| role="presentation" class="wikitable mw-collapsible"
| <strong>Lorem ipsum</strong>
|-
| Lorem ipsum dolor sit amet
|}</syntaxhighlight>
|style="width:50%;"|
{| role="presentation" class="wikitable mw-collapsible"
| <strong>Lorem ipsum</strong>
|-
| Lorem ipsum dolor sit amet
|}
|}

More complex data tables can also be collapsible.
