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.

The template does not provide a parameter to designate whether the link starts at a show or hide state. 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.

Do not use this template to hide content in articles. This violates the WP:Manual of Style § Scrolling lists and collapsible content and WP:Accessibility guidelines. This template is intended for use in pages in namespaces other than the article namespace.

Usage

Full syntax

{{Hidden
| expanded=true  <!--(omit for initial hidden state)-->
| style = 
| headerstyle = 
| header = 
| contentstyle = 
| content =

|fw1= |fw2= |bg1= |bg2= |ta1= |ta2=
}}

Parameters

Only two parameters are required for this template:

header

text for header (title); alternative to using unnamed parameter {{{1}}}

content

text for body (content); alternative to using unnamed parameter {{{2}}}

Optional

style

CSS styling for template overall.

headerstyle

CSS styling for title (header).

contentstyle

CSS styling for the hidden content.

expanded

any nonblank value (e.g. |expanded=on) will cause the template to be initially expanded by default.

multiline

any nonblank value (e.g. |multline=y) will reduce the line-height of the title and add some padding to avoid overlap with the show/hide button.

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

Examples

Issues

Show/hide button overlap

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

Possible workaround is to use |multiline=y:

"{{hidden|multiline=y|Lorem ipsum dolor sit amet, consectetur adipisicing 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.|def}}" gives "

Lorem ipsum dolor sit amet, consectetur adipisicing 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.

Example with long header

abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc

def

Above example with workaround:

"{{hidden|multiline=y|abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc abc |def}}" gives "
