Template:Collapsible option
From Zoophilia Wiki
Use {{Template name|state=collapsed}} or {{Template name|state=uncollapsed}} to instantiate the template in, respectively, its collapsed (hidden) or uncollapsed (expanded) state.
Use {{Template name|state=autocollapse}} to collapse the template only if there is another template of the same type on the page.
