{{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
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}}, if the template is coded that way. 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):
Initial visibility: currently defaults to autocollapse
To set this template's initial visibility, the |state= parameter may be used:
|state=collapsed:{{Collapsible option|state=collapsed}}to show the template collapsed, i.e., hidden apart from its title bar|state=expanded:{{Collapsible option|state=expanded}}to show the template expanded, i.e., fully visible|state=autocollapse:{{Collapsible option|state=autocollapse}}
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.
This possibility is enabled by including:
{{{1|}}}as part of a collapsible template's|state=parameter – for instance, as|state={{{state|{{{1|}}}}}}or|state={{{state|{{{1|<noinclude>expanded</noinclude>}}}}}}, etc.<noinclude>,<includeonly>as part of a collapsible template'sstateargument – for 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
To change the default state {{Collapsible option}} uses, add the parameter |default=collapsed or |default=expanded accordingly. To restore the default, remove any |default= previously included.
The |default=collapsed option must not be used in main article content in mainspace, e.g. to hide tables of information, or to cram extraneous details into infoboxes.
