==Reference lists: columns==
{{Shortcut|H:REFCOLS}}
{{Hatnote|Columns are not supported by Internet Explorer 9 and below; see {{tl|Reflist}} for technical details}}
When using {{tl|Reflist}} or {{tag|references|s}}, the list can be split into columns. The {{tag|references|s}} tag provides a default column width of 30 [[em (typography)|em]]. {{tl|Reflist}} can be used to set a different column width:
:{{tlx|Reflist|<var>xx</var>em}}, where <var>xx</var> is the column width in em.

The number of columns will automatically be adjusted to the width of the display. It should be used only when necessary, as both the tag and the template have built-in auto-formatting capabilities providing a useful default display in most scenarios.

The [[Template:Reflist#Columns|set columns feature]] is now [[deprecation|deprecated]] in favor of the option described above, which is better suited to flexible formatting for a variety of display screen sizes, ranging from mobile phones and tablets to wide-screen "cinema" displays. Forcing a fixed number of columns has been disabled in mobile view.

The number of columns to use is up to the editor, but some major practices include:
* {{tlx|Reflist|30em}}: Where there are many footnotes plus a page-width Bibliography subsection: see {{oldid|Ebola virus disease|561190497#References|Ebola virus disease (06:28, 23 June 2013)}}
* {{tlx|Reflist|20em}}: Where {{sfnote}} are used; see {{oldid|NBR 224 and 420 Classes|442508215#Notes|NBR 224 and 420 Classes (13:32, 1 August 2011)}}.

For example:
Using {{tlx|Reflist|30em}} will create columns with a minimum width of 30 em,
{{markup|title=30em wide columns
|<nowiki>Lorem ipsum.<ref>Source name, access date, etc.</ref>

Lorem ipsum dolor sit amet.<ref>Source name, access date, etc.</ref>

==References==
{{Reflist|30em}}</nowiki>
|Lorem ipsum.<ref>Source name, access date, etc.</ref>
Lorem ipsum dolor sit amet.<ref>Source name, access date, etc.</ref>

{{Fake heading|sub=3|References}}
{{Reflist|30em}}
