This template's initial visibility currently defaults to autocollapse
, meaning that if there is another collapsible item on the page (anavbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
To change this template's initial visibility, the |state=
parameter may be used:
{{BASEPAGENAME|state=collapsed}}
will show the template collapsed, i.e. hidden apart from its title bar.{{BASEPAGENAME|state=expanded}}
will show the template expanded, i.e. fully visible.![]() | This template is used on approximately 139,000 pages. To avoid major disruption and server load, any changes should be tested in the template's /sandboxor/testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
{{Collapsible option}}
is a utility template provides a standardised message for transclusionontemplate documentaion pages for templates whose collapsibility may be managed by the parameter |state=
.
It can be used on either the template page itself (wrapped within <noinclude>...</noinclude>
tags), but it is almost always better to place it in the template's {{documentation subpage}}
.
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):
This template's initial visibility currently defaults to autocollapse
, meaning that if there is another collapsible item on the page (anavbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
To change this template's initial visibility, the |state=
parameter may be used:
{{Collapsible option|state=collapsed}}
will show the template collapsed, i.e. hidden apart from its title bar.{{Collapsible option|state=expanded}}
will show the template expanded, i.e. fully visible.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's state
argument – 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.
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. (For more information, see Wikipedia:Manual of Style § Scrolling lists and collapsible content.) This option is permissible in navboxes, which are not part of the article content per se.
If the template name given to {{Collapsible option}}
includes a forward-slash (virgule) character – / – then 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).
