{{collapsible navfobox}} is used almost identically to {{navfobox}}. The difference is that sections are collapsible. Currently, all sections are collapsible by default and there is no option to change this. Setting |collapsed= to any non-blank value will cause the navfobox to start collapsed by default, shown to the right. Instead setting |fullCollapsed= to any non-blank value will cause every section to start collapsed by default as well.
