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:

• {{New Democratic Party|state=collapsed}} will show the template collapsed, i.e. hidden apart from its title bar.
• {{New Democratic Party|state=expanded}} will show the template expanded, i.e. fully visible.

This template should be included at the bottom of articles about New Democratic Parties in Canada.
