Template:Hidden/doc

This is a documentation subpage for Template:Hidden.
It may contain usage information, categories and other content that is not part of the original template page.

This template is used on approximately 353,000 pages, or roughly 1878% of all pages.
To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them.

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.

Usage

Full syntax

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

|titlebgcolor= |contentbgcolor= |ta1= |ta2= |fw1= |fw2= |class= |border=
}}

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.
border: border around the template.
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.
class: add additional class attributes affecting the entire template.

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

Issues

Show/hide button overlap

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

{{Template:Hidden|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}} →

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

[1]

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.

def

"

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 "

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
