Template:Collapsible list

Template documentation[view] [edit] [history] [purge]

This template produces a collapsible list. It is possible to set CSS styles for the "frame" (the ‎<div>...‎</div> tags surrounding the list), for the list title, and for the list items. The template supports an unlimited number of list items.

This template is typically used in infoboxes and navboxes; it should not normally be used in regular article content, per .

Regarding using this template in infoboxes, MOS:DONTHIDE acknowledges an exception:

A few infoboxes also use pre-collapsed sections for infrequently accessed details. If [such] information ... seems extraneous or trivial enough to inspire pre-collapsing it, consider raising a discussion on the article (or template) talk page about whether it should be included at all.

Syntax

{{Collapsible list
 | expand = 
 | framestyle = 
 | titlestyle = 
 | title = 
 | liststyle = 
 | hlist = 
 | bullets = 
 | 1 =     <!--(First item in list; the "1 =" is usually not required)-->
 | 2 =     <!--(Second item in list; ditto)-->
 | 3 =     <!--(Third item in list; etc.)-->
 | <!-- etc -->
}}

Parameters

expand	Any text in this parameter (including "no") sets the list's default state to expanded rather than collapsed. Omit the parameter or leave it blank to set the default state to collapsed.
framestyle	Custom CSS styling applied the template overall (title and list).
titlestyle	Custom CSS styling applied to the title.
title	The list's title (always on view beside the list's [show/hide] link).
liststyle	Custom CSS styling applied to the list (specifically, to the ‎<ul>...‎</ul> tags delimiting the list).
hlist	Include as |hlist=on, |hlist=true, etc to produce a horizontal rather than vertical list.
bullets	Include as |bullets=on, |bullets=true, etc to place a bullet point before each list item.
Unnamed parameters (first, second, third...)	The list items (in the order in which they will appear). If none are supplied, the template outputs nothing.
