Usage
This navigational template is included by {{interface explanation}}, which is used on MediaWiki talk: pages to describe the relevant message.
This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
To change this template's initial visibility, the |state= parameter may be used:
{{MediaWiki messages|state=collapsed}}will show the template collapsed, i.e. hidden apart from its title bar.{{MediaWiki messages|state=expanded}}will show the template expanded, i.e. fully visible.
