Template:Hidden

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 allorreveal all.

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

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

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

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}}}

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".

In this example only the two required parameters are specified.

{{hidden|Title text here|Body text line 1<br/>Body text line 2}}

{{hidden
|Title text here
|Body text line 1<br/>Body text line 2
|headerstyle=background:#ccccff
|style=text-align:center;
}}

{{hidden
| style = border: 1px dashed red; width: 50%;
| headerstyle = background: #ccccff; font-size: 110%;
| contentstyle = text-align: center; color: green;
| header = Title text here
| content = Body text line 1<br />Body text line 2<br />Body text line 3
}}

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

Possible workaround is to use |multiline=y:

Example with long header

Above example with workaround:

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