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.
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, i.e.
- How to manage this template's visibility
- Use
{{Template name |collapsed}}to show this template in its collapsed (hidden) state. - Use
{{Template name |expanded}}to show this template in its expanded (fully visible) state. - Use
{{Template name |autocollapse}}to show this template in its collapsed (hidden) state only if there is another template of the same type on the page. (This is usually the default, i.e. doesn't usually need specifying.)
