When it is viewed directly, links using variables may appear broken; do not replace these with hardcoded page names or URLs.
This template is designed to be used with {{Navbox}} or {{Navbox generic}}, navigational templates which 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}} or {{Navbox generic}}. A subgroup may contain up to 12 list items.
(i.e. list1, list2, ... list12) 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 listn may be preceded by a corresponding groupn 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.
groupn
(i.e. group1, group2, ... group12) If specified, text appears in a header cell displayed to the left of listn. If omitted, listn uses the full width of the table. The background color defaults to #ddf (a truncated form of #ddddff), but can be changed via the groupstyle parameter (see below).
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 groupN 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;
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.
The following is an example of Navbox generic subgroup used within a Navbox template. Below that is the code used to generate this navigation box, with the subgroup template shown in bold text.
{{Navbox
| name = Protected Areas of Colorado
| title = Protected Areas of Colorado
| liststyle = background-color: transparent;
| group1 = National Park Service
| list1 =
{{Navbox generic 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 odd-numbered rows (list1, list3) and the links to even-numbered rows (list2, list4), then using oddstyle to set the background color.
