This template creates adynamic navigation box using style sheet declarations inMediaWiki:Common.css and Javascript code inMediaWiki: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 forcollapse all orreveal all.
Generally, collapsible templates should not be used in articles. For allowable uses and other considerations, please seeMOS:COLLAPSE.
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 theuser preference "justify paragraphs".
