Editing Template:Navbox/doc (section)

=== Setup parameters ===

; ''name''<nowiki>*</nowiki>
: The name of the template, which is needed for the view, discuss, and edit icon links to work properly on all pages where the template is used. You can enter <code><nowiki>{{subst:PAGENAME}}</nowiki></code> for this value as a shortcut. The name parameter is only mandatory if a <code>title</code> is specified and the <code>border</code> parameter is not set.

; ''state''<nowiki>*</nowiki> <span style="font-weight:normal;">[<code>uncollapsed, collapsed, off</code>]</span>
:* Defaults to <code>uncollapsed</code>.
:* If set to <code>collapsed</code>, the navbox will always start out in a collapsed state.
:* If set to <code>off</code>, the navbox will always be expanded with no [hide] link on the right.
:* If set to anything other than <code>collapsed</code>, or <code>off</code> (such as <code>uncollapsed</code>), the navbox will always start out in an expanded state, but have the "hide" button.

: To define a default initial state for a navbox that can be overridden in an article:

:* In your intermediate template, create a parameter also named "state" as a pass-through:
:: <tt><nowiki>| state = {{{state<includeonly>|your_desired_initial_state</includeonly>}}}</nowiki></tt>
:* The <nowiki><includeonly>|</nowiki> will expand the template when viewing the template page by itself.

: Example: {{tl|Absalom navbox}} with autocollapse as the default initial state. [[The Docks]] transcludes it and has only one navbox, so the Absalom navbox shows. [[Absalom]] has two navboxes, so the Absalom navbox collapses.
<!-- No PFW navboxes use expanded as the default
Example: {{tl|Historical currencies of Hungary}} with expanded as the default initial state. All transcluding articles shows the content by default, unless there were an hypothetical article that specifies state = collapsed when transcluding.
