Initial visibility: currently defaults to autocollapse
To set this template's initial visibility, the |state=parameter may be used:
|state=collapsed: {{Regions of the world|state=collapsed}} to show the template collapsed, i.e., hidden apart from its title bar
|state=expanded: {{Regions of the world|state=expanded}} to show the template expanded, i.e., fully visible
|state=autocollapse: {{Regions of the world|state=autocollapse}}
shows the template collapsed to the title bar if there is a {{navbar}}, a {{sidebar}}, or some other table on the page with the collapsible attribute
shows the template in its expanded state if there are no other collapsible items on the page
If the |state= parameter in the template on this page is not set, the template's initial visibility is taken from the |default= parameter in the Collapsible option template. For the template on this page, that currently evaluates to autocollapse.
How to manage this template's collapsible groups/sections option
This template includes collapsible groups/sections. When it first appears, one of these groups/sections may be set to be visible ("expanded") while the others remain hidden ("collapsed") apart from their titlebars. To achieve this, include the parameter|name where name is one of the following words that identify the groups/sections (omit any speech or quotation marks):
Africa=expanded
Asia=expanded
Europe=expanded
N America=expanded
Oceania=expanded
S America=expanded
Polar=expanded
Seas=expanded
For example: {{Regions of the world |S America=expanded}}
