साचा:Collapsible option/doc

This is a documentation subpage for साचा:Collapsible option.
It contains usage information, categories and other content that is not part of the original साचा page.

{{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}}. 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}}
- 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.

(This possibility is enabled by including:

{{{1|}}} as part of a collapsible template's state parameterसाचा: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 argumentसाचा: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

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

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 {{PAGENAME}} rather than the default {{BASEPAGENAME}} is used to display it).
