Template:Collapsible option

How to manage this template's visibility

• Use {{Template name |state=collapsed}}  to show this template in its collapsed (hidden) state.
• Use {{Template name |state=expanded}}  to show this template in its expanded (fully visible) state.
• Use {{Template name |state=autocollapse}}  to show this template in its collapsed (hidden) state only if there is another template of the same type on the page.
• Unless set otherwise (see state parameter within the template's code), autocollapse is the default state.

Template documentation[view] [edit] [history] [purge]

The {{collapsible option}} template gives a standardised message for transclusion on template pages whose templates include a state parameter (through which their collapsibility may be managed).

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

Usage

Indicating optional use of state name

If, in a template where {{collapsible option}} has been transcluded, that template's state parameter has been enabled such that it need not be named when the template is called – i.e., the state parameter includes {{{1| }}}, e.g.:

|state = {{{state|{{{1|}}}}}}

or

|state = {{{state|{{{1|<noinclude>expanded</noinclude>}}}}}}

etc

then:

{{collapsible option |statename=optional}}

removes the instances of |state= from the {{collapsible option}} message, and will display as:

Changing default
