Template documentationInitial visibility: currently defaults to autocollapse
To set this template's initial visibility, the |state= parameter may be used:
|state=collapsed:((Prehistoric Europe|state=collapsed))to show the template collapsed, i.e., hidden apart from its title bar|state=expanded:((Prehistoric Europe|state=expanded))to show the template expanded, i.e., fully visible|state=autocollapse:((Prehistoric Europe|state=autocollapse))
If the |state= parameter in the template on this page is not set, the template's initial visibility is taken from the |default= parameter in the Collapsible option template. For the template on this page, that currently evaluates to autocollapse.
