This template is used in MediaWiki:Citethispage-content, and on approximately188,000 pages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them.
This template creates horizontal lists. Each item in the list may be individually styled with CSS.
Lists output by {{Flatlist}} and {{Horizontal list}} are semantically and visually identical, and differ only in the wiki markup used to create the lists.
{{horizontal list
|first item|second item|third item|...
|class = class for div tag
|style = style for div tag
|list_style = style for ul tag
|item_style = style for all li tags
|item1_style = style for first li tag
|item2_style = style for second li tag
|...
|indent = the number of tabs to indent
}}
Positional parameters (1, 2, 3...): these are the list items. If no list items are present, the module will output nothing.
class: a custom class for the <div>...</div> tags surrounding the list. Set to inline when using {{horizontal list}} inside text.
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 <ul>...</ul> tags around the list. 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.
Avoid using the style white-space:nowrap in the item_style parameter, because it will have the unintended effect of avoiding line breaks anywhere in the list, instead of just inside the list item; the workaround is to move this style in the list_style parameter, and then insert {{Wbr}} at the beginning of each item value, to insert an invisible word-break opportunity (and not at end of the item value, as the word-break would occur just before the trailing spaced-bullet separator).
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.
indent: the number of tabs to indent the list. Default value is 0.
{{Horizontal list}} will produce Lintererrors if placed inside a template that uses <span>...</span> tags, such as {{small}}, {{larger}}, etc. To avoid this, use the substitutions from the table below:
