This module outputs an unbulleted list. It has two functions: unbulleted, for a normal unbulleted list, and hlist, for a horizontal list using the hlist class (see WP:HLIST). It supersedes the templates {{unbulleted list}} and {{hlist}}.

|first item|second item|third item|...
|class     = class
|style     = style
|ul_style  = style for ul tag

|li_style1 = style for first li tag |li_style2 = style for second li tag |...
|indent    = indent for the list
}}

Arguments passed from parent template

{{#invoke:unbulleted list|hlist}}

Parameters

• 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, e.g. plainlinks.
• style - a custom css style for the <div>...</div> tags surrounding the list, e.g. font-size: 90%;.
• ul_style - a custom css style for the <ul>...</ul> tags around the list. The format is the same as for the |style= parameter.
• li_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.
• li_style1, li_style2, li_style3... - custom css styles for each of the list items. The format is the same as for the |style= parameter.
• indent - for horizontal lists only, this parameter indents the list. 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.
