This template is used on many pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.
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:
{{National Register of Historic Places|state=collapsed}} will show the template collapsed, i.e. hidden apart from its title bar.
{{National Register of Historic Places|state=expanded}} will show the template expanded, i.e. fully visible.
