This template usesLua: Module:Navbox (sandbox)

This template produces anavigation template that has groups of relevant articles on a certain topic. All groups are hidden by default. However, with a parameter call, an individual group can be shown that has the other articles in the same group.

Please remove the parameters that are left blank. The template currently supports up to 20 groups/lists but more can be added if needed. You should use a minimum of two groups/lists; otherwise, use{{Navbox}} instead.

{{Navbox with collapsible groups| name={{subst:PAGENAME}}| title=| listclass= hlist| state={{{state|}}}| selected={{{selected|{{{1|}}}}}}| above=| image=| abbr1=| group1=| list1=| abbr2=| group2=| list2=<!--[etc, to:]-->| abbr20=| group20=| list20=}}

This template shares many common parameters with its sister templates{{Navbox}} and{{Navbox with columns}}. The common parameters are marked with a cross^†. Please refer to the documentation of{{Navbox}} for more in depth descriptions and examples of those parameters.

name^†

The name of the template. The name of this template, for example, is "Navbox with collapsible groups".

state^†[uncollapsed, collapsed, plain, off]

The initial state of the show/hide feature for the main title. See{{Navbox}} for more information. Does not affect display or hiding of group items, seestate_n, below.

navbar^†

Possible values areplain,off, and the default value of blank. See{{Navbox}} for more information.

border^†

Possible values arechild,none, and the default value of blank. Set tochild if you wish to use the navbox inside of another navbox; with this option, the child navbox is borderless and fits snuggly inside of its parent navbox. The parent navbox may be the list area of{{Navbox}}, the columns of a{{Navbox with columns}}, or a list area of{{Navbox with collapsible groups}}. See{{Navbox}} for more information and examples.

title^†

The title of the template, displayed centered in the titlebar at the top of the template.

above^†

Text or other elements to appear above groups/lists.

image^†

Image to the right of all of the groups/lists.

imageleft^†

Image to the left of all of the groups/lists.

below^†

Text or other elements to appear below the groups/lists.

group_n^†

The title of each section.

list_n^†

The content/wikilinks that will be shown in the group.Use dots or bullets as separators (see theSee also section). A{{Navbox}} or{{Navbox with columns}} can optionally be used here with itsborder = child parameter set. If this is done, leave the corresponding group_n blank, as the child navbox will already provide the collapsible feature.

abbr_n

This is the abbreviation of the group. Seeselected parameter immediately below to see how to use this parameter. This parameter is optional, but recommended.

selected

If the value ofselected equals the value ofabbrn, then list_n is uncollapsed and all other lists are collapsed. Ifselected is left blank, or if it does not match anyabbrn, then all groups are collapsed. Usually this parameter should be set to{{{1|}}}. Since this template is a base template for others, there has to be a way to pass the group parameter from the article, to the secondary template to this one.

The collapsed/uncollapsed options can be listed on the template's page by using the{{Collapsible sections option}} template in the <noinclude> part of the page.

state_n[uncollapsed, collapsed, plain, off]

The initial collapsible state of list_n. Set to collapsed by default. Overridden to uncollapsed ifselected equalsabbrn.

image_n

An image to appear in the list_n content area on the right side.

imageleft_n

An image to appear in the list_n content area on the left side.

bodystyle^†

CSS style/s to apply to the entire template

titlestyle^†

CSS style/s to apply to titlebar; usuallybackground:color. The color of wikilink text must be manually changed using span tags. For example usetitle = [[Scouting|<span>Scouting</span>]] to change the color of the link to ivory. The [show]/[hide] button and the vde link button use the color set in the titlestyle parameter. Here is an example of setting the titlestyle:

titlestyle = background:darkgreen;color:ivory;

abovestyle^†

belowstyle^†

CSS style/s to apply to theabove andbelow parameters, respectively.

basestyle^†

CSS style/s to apply to thetitle,above,below, andgroup_n parameters, all at the same time.

imagestyle^†

CSS style/s to apply to theimage parameter. Does not get applied to the image_n parameters.

imageleftstyle^†

CSS style/s to apply to theimageleft parameter. Does not get applied to the imageleft_n parameters.

To nest a navbox inside a Navbox with collapsible groups, set thelistn parameter tochild orsubgroup. Elements of the child navbox can be specified by prependingchildn_,subgroupn_, or justn_ to the parameter names (e.g.1_list1). Child navboxes can be nested by adding an additional prefix (e.g.1_1_list1). The basic code for doing this is as follows (which adds a subgroup for the first group/list area):

{{Navbox with collapsible groups| name={{subst:PAGENAME}}| title= Title| group1= Group Title| list1= child| 1_title= [optional]| 1_group1= [optional]| 1_list1= child| 1_1_title= [optional]| 1_1_group1= [optional]| 1_1_list1=     ...list contents...  ......}}

{{Navbox with collapsible groups}} or{{Navbox with columns}} can be nested by setting then_type parameter to "with collapsible groups" or "with columns".

This navbox template works in conjunction with two other templates:{{Navbox}} and{{Navbox with columns}}. All three of these templates share common parameters for consistency and ease of use (such parameters are marked with an asterisk (*) in theparameter descriptions list atTemplate:Navbox/doc). Most importantly, each template can be used as a child of one another. Using the inline notation, then_type= parameter can be set towith columns orwith collapsible groups to set the type of that child navbox, as shown in the example below. Press the edit button for the section to view the code.

You can also nest these navbox templates by using the|border=child parameter, or by specifying the first unnamed parameter to bechild. For example:{{Navbox|child ...}},{{Navbox with columns|child ...}} or{{Navbox with collapsible groups|child ...}}. Note that this style of nesting can lead to a large increase in the template'spost-expand include size.

• This template is a shortcut for the syntax shown atTemplate:Navbox/doc § Multiple show/hides in a single container. It usesModule:Navbox to render the actual navbox.
• Navbox templates, including this one, are a major contributor to thepost-expand include size of pages, and can cause pages to exceed the limit and not render correctly. There are a few ways to mitigate this.
  • {{Navbox with collapsible groups}} can be replaced with{{#invoke:Navbox|with collapsible groups}}, which approximately halves the include size
  • Nesting other templates inside of a navbox can cause the include size increase by a factor of two or more. This template currently supports the same in-line child syntax documented atTemplate:Navbox/doc#Child navboxes, which mitigates this, but only for plain Navboxes, Navboxes with collapsible groups, and Navboxes with columns.

• {{Navboxes}} (and{{Navboxes top}})
• {{Collapsible sections option}}
• {{Nowrap begin}} – Provides an explanation of the preferred method of using bullets or pipes to delimit list items. Deprecated; use thehlist class.
