This template'sinitial visibility currently defaults toautocollapse, meaning that if there is another collapsible item on the page (anavbox, sidebar, ortable 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 onapproximately 146,000 pages. To avoid major disruption and server load, any changes should be tested in the template's/sandbox or/testcases subpages, or in your ownuser subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on thetalk page before implementing them.
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}}.
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.
If the template name given to{{Collapsible option}} includes a forward-slash (virgule) character –/ – then the parameter|nobase= (set toon,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).
