{{Collapsible option}} provides a standardised message for transclusion on the pages of collapsible templates whose collapsibility may be managed by the parameter state.

It may be used on either the template page itself (wrapped within <noinclude>...</noinclude> tags) or on the template's {{documentation subpage}}.

Indicating optional use of state name[edit]

The state parameter used to manage collapsible templates need not always be named explicitly, i.e. {{[Template name]|state}} can be the same as {{[Template name]|state=state}}. To indicate this in the {{Collapsible option}} message, add the parameter |statename=optional. This modifies the message so that it reads (if it were used for itself):

Template:Collapsible option

(This possibility is enabled by including:
  • {{{1|}}} as part of a collapsible template's state parameterTemplate:Spaced ndashfor instance, as |state={{{state|{{{1|}}}}}} or |state={{{state|{{{1|<noinclude>expanded</noinclude>}}}}}}, etc.
  • <noinclude>,<includeonly>as part of a collapsible template's state argumentTemplate:Spaced ndashfor instance, as |state={{{state<includeonly>|collapsed</includeonly>}}}
If, however, the template includes collapsible sections within itself (e.g. {{Navbox with collapsible groups}}), then enabling this possibility may introduce ambiguity as regards what is to be collapsed or expanded. In those instances, therefore, the requirement to use |state= should be retained.)

Changing the default state reported[edit]

To change the default state {{Collapsible option}} reports in its second bullet-point, add the parameter |default=collapsed or |default=expanded accordingly. To restore the default report, remove any |default= previously included.

nobase[edit]

If the template name given to {{Collapsible option}} includes a (forward-)slash character ("/"), the parameter |nobase= (set to "on", "true", etc.) will need to be added so that the name is displayed correctly (i.e. so that Template:Wikivar rather than the default Template:Wikivar is used to display it).
