Template:Hidden/doc

This template creates a dynamic navigation box using style sheet declarations in MediaWiki:Common.css/Nav.css and JavaScript code in MediaWiki:Common.js/CollapsibleElements.js. It displays the first parameter (the heading) with a [show] link on the right. If [show] is clicked by the user, the second parameter (the body) is displayed below the heading and the [show] link becomes [hide]. Clicking on [hide] then hides the body again and the [hide] link becomes [show] again.

The template does not provide an argument to designate the initial state of the show/hide control. In the nested case, show/hide controls in hidden content retain their state. There is no facility for collapse all or reveal all.

Usage
Only two parameters are required for this template:
 * header : text for header (or title); alternative to using unnamed parameter
 * content : text for content (or body); alternative to using unnamed parameter

Optional parameters

 * style : add CSS to the main div.
 * headerstyle : add CSS to the header.
 * contentstyle : add CSS to the content box.
 * noprint : if anything is put in for this parameter the hidden box (and its contents) won't show up in the printed version.

Note: This template will not respect the user preference "justify paragraphs".

The simplest
In this example only the two required parameters are specified.

Sections
Sections included inside a hidden block result in broken anchors in the table of contents at the top of the page.
