Initial visibility
To set the template's initial visibility, the |state= parameter may be used:
|state=collapsed: {{Nevada cities and mayors of 100,000 population|state=collapsed}} to show the template collapsed, i.e., hidden apart from its title bar|state=expanded: {{Nevada cities and mayors of 100,000 population|state=expanded}} to show the template expanded, i.e., fully visible|state=autocollapse: {{Nevada cities and mayors of 100,000 population|state=autocollapse}}
If the |state= parameter is not set, the template's initial visibility is taken from the |default= parameter in the template. For this template, that currently evaluates to autocollapse.
