Template:Hidden/doc

This template creates a dynamic navigation box using style sheet declarations in MediaWiki:Common.css and Javascript code in MediaWiki:Common.js. In a saved, rendered page this template creates a clickable link that toggles between [show] and [hide]. It displays the first parameter (the heading) with a [show] link on the right. If [show] is clicked by the user, it displays the second parameter (the body) below the heading and the [show] link becomes [hide]. Clicking on [hide] then hides the body and the [hide] link becomes [show] again.

If this template is nested in another, the show/hide links in the hidden content keep their state; there is no parameter for collapse all or reveal all.

Generally, collapsible templates should not be used in articles. For allowable uses and other considerations, please see MOS:COLLAPSE.

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

Optional
Note: This template will not respect the user preference "justify paragraphs".
 * style       : CSS styling for template overall.
 * border      : default is none.
 * headerstyle : CSS styling for title (header).
 * contentstyle : CSS styling for the hidden content.
 * expanded    : any nonblank value (e.g. on) will cause the template to be initially expanded by default.
 * multiline   : any nonblank value (e.g. y) will reduce the line-height of the title and add some padding to avoid overlap with the show/hide button.

Basic
In this example only the two required parameters are specified.

Show/hide button overlap
With ta1=right or a long header, the header may overlap the show/hide button:

" " gives ""
 * Possible workaround is to use y:

Example with long header

" " gives ""
 * Above example with workaround:

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