To change this template's initial visibility, the |state= parameter may be used:

• ((United States Department of Homeland Security|state=collapsed)) will show the template collapsed, i.e. hidden apart from its title bar.
• ((United States Department of Homeland Security|state=expanded)) will show the template expanded, i.e. fully visible.
