This module is used in MediaWiki:Citethispage-content. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid large-scale disruption, any changes should first be tested in this template's /sandbox or /testcases subpage, or in your own user space. The tested changes can then be added in one single edit to this template. Please discuss any changes at the talk page before implementing them.
This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing.
This module depends on the following other modules:
This module outputs various kinds of lists. At present, it supports bulleted lists, unbulleted lists, horizontal lists, ordered lists (numbered or alphabetical), and horizontal ordered lists. It allows for easy css styling of the list or of the individual list items.
{{#invoke:list|function
|first item|second item|third item|...
|start = start number for ordered lists
|type = type of numbering for ordered lists
|list_style_type = type of marker for ordered lists (uses CSS)
|class = class
|style = style
|list_style = style for the list
|item_style = style for all list items
|item1_style = style for the first list item |item2_style = style for the second list item |...
|item1_value = value for the first list item |item2_value = value for the second list item |...
|indent = indent for horizontal lists
}}
Positional parameters (1, 2, 3...) - these are the list items. If no list items are present, the module will output nothing.
start - sets the start item for ordered lists. This can be a start number for numbered lists, or a start letter for alphabetical lists. Horizontal ordered lists only support numbers.
type - the type of marker used in ordered lists. Possible values are "1" for numbers (the default), "A" for uppercase letters, "a" for lowercase letters, "I" for uppercase Roman numerals, and "i" for lowercase Roman numerals. Not supported in horizontal ordered lists. See also the list_style_type parameter.
list_style_type - the type of marker used in ordered lists. This uses CSS styling, and has more types available than the type parameter, which uses an html attribute. Possible values are listed at MDN's list-style-type page. Support may vary by browser. list-style-type is an alias for this parameter.
class - a custom class for the <div>...</div> tags surrounding the list, e.g. plainlinks.
style - a custom css style for the <div>...</div> tags surrounding the list, e.g. font-size: 90%;.
list_style - a custom css style for the list itself. The format is the same as for the |style= parameter.
item_style - a custom css style for all of the list items (the <li>...</li> tags). The format is the same as for the |style= parameter.
item1_style, item2_style, item3_style... - custom css styles for each of the list items. The format is the same as for the |style= parameter.
item1_value, item2_value, item3_value... - custom value for the given list item. List items following the one given will increment from the specified value. The value should be a positive integer. (Note that this option only has an effect on ordered lists.)
indent - this parameter indents the list, for horizontal and horizontal ordered lists only. The value must be a number, e.g. 2. The indent is calculated in em, and is 1.6 times the value specified. If no indent is specified, the default is zero.
