Add {{String-handling templates}}
to the bottom of a documentation page of a template listed in the navbox.
How to manage this template's collapsible groups/sections option
- This template includes collapsible groups/sections. When it first appears, one of these groups/sections may be set to be visible ("expanded") while the others remain hidden ("collapsed") apart from their titlebars. To achieve this, include the parameter
|name
where name is one of the following words that identify the groups/sections (omit any speech or quotation marks):
Initial visibility: currently defaults to expanded
To set this template's initial visibility, the |state=
parameter may be used:
|state=collapsed
: {{String-handling templates|state=collapsed}}
to show the template collapsed, i.e., hidden apart from its title bar
|state=expanded
: {{String-handling templates|state=expanded}}
to show the template expanded, i.e., fully visible
|state=autocollapse
: {{String-handling templates|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 expanded
.
