Template:Navbox subgroup

This template employs some extremely complicated or esoteric features of template syntax. Please do not attempt to alter it unless you are certain that you understand the setup and are prepared to repair/revert any consequent collateral damage if the results are unexpected. Any experiments should be conducted in a sandbox or your userspace.

This template is designed to be used with {{Navbox}} or other navigational templates that allow creating lists of links with groups headers or titles. This template allows the creation of subgroups that can be assigned to a list item within {{Navbox}}. A subgroup may contain up to 20 list items.

{{Navbox subgroup
| groupstyle = 
| liststyle  = 

| group1 = 
| list1  = 
| group2 = 
| list2  = 
...
| group20 = 
| list20  = 
}}

This template employs all parameters of {{Navbox}}. Please see the documentation there for more complete descriptions. In fact, the only differences between this template and {{Navbox}} are as follows:

• The border parameter defaults to "child"
• The group padding defaults to 0.75em on the left/right, and can only be changed with the grouppadding parameter. This is done to prevent the Internet Explorer box model bug from affecting the width of groups.

Everything else is exactly the same as {{Navbox}}.

Only the most common parameters are listed below.

list_n

(i.e. list1, list2, ... list20) The body of the template, usually a list of links. Format is inline. At least one list parameter is required; each additional list is displayed in a separate row of the table. Each list_n may be preceded by a corresponding group_n parameter, if provided (see below). The background color of the list items (and the entire table) defaults to transparent, therefore it displays the same background color used in the parent navigation box.

group_n

(i.e. group1, group2, ..., group20) If specified, text appears in a header cell displayed to the left of list_n. If omitted, list_n uses the full width of the table. The background color defaults to #e6e6ff, but can be changed via the groupstyle parameter (see below).

bodystyle

Specifies CSS styles to apply to the template body. Examples:

background:#nnnnnn;

text-align:[right/center/left/justified];

groupstyle

CSS styles to apply to the group_n cells. This option overrides any styles that are applied to the entire table. Examples:

background:#nnnnnn;

text-align:[left/center/right];

vertical-align:[top/middle/bottom];

white-space:nowrap;

grouppadding

CSS style to specify group padding. Should usually be specified using em units. It is recommended to leave this parameter alone and use the default padding. Examples:

grouppadding = 0em 1em; (1em on left/right, 0em on top/bottom)

grouppadding = 0em 0.5em 0em 1em; (0em top, 0.5em right, 0em bottom, 1em left)

liststyle

CSS styles to apply to all lists. Overridden by the oddstyle and evenstyle parameters (if specified) below.

oddstyle

evenstyle

CSS styles to apply to the odd-numbered list items (list1, list3, etc) or even-numbered list items (list2, list4, etc), respectively. Typically used to set background color (background:#nnnnnn;) in order to achieve an alternating background color between odd and even-numbered lists.

evenodd [swap, even, odd, off]

If set to swap, then the automatic striping of even and odd rows is reversed. Normally, even rows get a light gray background for striping; when this parameter is used, the odd rows receive the gray striping instead of the even rows. Setting to even or odd sets all rows to have that striping color. Setting to off disables automatic row striping. NOTE: Due to system limitations, do not use a semi-colon to close this command.

If multiple {{Navbox subgroup}} templates are used inside of a parent {{Navbox}}, it generally looks better if the width of the groups matches up. In order to do this, one must set the groupwidth parameter:

groupwidth = 10em

An alternative way is to set the groupstyle parameters to contain the desired width, and the liststyle parameters to have width:auto (due to HTML/CSS reasons). For example, place the following code in each {{Navbox subgroup}} to adjust the widths:

groupstyle = width:10em;

liststyle = width:auto;

• NOTE: For the groupstyle widths to work, you must set the liststyle width to "auto".

If you also use the image or imageleft parameters, then you will most likely also need to set their width manually using the imagestyle and imageleftstyle parameters.

The following is an example of Navbox subgroup used within a Navbox template.

{{Navbox
| name   = Protected Areas of Colorado
| title  = Protected Areas of Colorado
| group1 = National Park Service
| list1  = 
  {{Navbox subgroup
   |group1 = National Parks
   |list1  = [[Black Canyon of the Gunnison National Park|Black Canyon of the Gunnison]]{{•}} [[Great Sand Dunes National Park and Preserve|Great Sand Dunes]]{{•}} [[Mesa Verde National Park|Mesa Verde]]{{•}} [[Rocky Mountain National Park|Rocky Mountain]]
   |group2 = National Monuments
   |list2  = [[Colorado National Monument|Colorado]]{{•}} [[Florissant Fossil Beds National Monument|Florissant Fossil Beds]]{{•}} [[Hovenweep National Monument|Hovenweep]]{{•}} [[Yucca House National Monument|Yucca House]]
   |group3 = National Historic Sites
   |list3  = [[Bent's Old Fort National Historic Site|Bent's Old Fort]]{{•}} [[Sand Creek Massacre National Historic Site|Sand Creek Massacre]]
   |group4 = National Recreation Area
   |list4  = [[Curecanti National Recreation Area|Curecanti]]
  }}
| group2 = National Forests
| list2  = [[Arapaho National Forest|Arapaho]]{{•}} [[Grand Mesa National Forest|Grand Mesa]]{{•}} [[Gunnison National Forest|Gunnison]]{{•}} [[Pike National Forest|Pike]]{{•}} [[Rio Grande National Forest|Rio Grande]]{{•}} [[Roosevelt National Forest|Roosevelt]]{{•}} [[Medicine Bow - Routt National Forest|Medicine Bow - Routt]]{{•}} [[San Isabel National Forest|San Isabel]]{{•}} [[San Juan National Forest|San Juan]]{{•}} [[Uncompahgre National Forest|Uncompahgre]]{{•}} [[White River National Forest|White River]]
}}

This example implements horizontal group headings by assigning the headings to list1 and list3 and the links to list2 and list4), then using list1style and list3style to set the background color of the headings.
