{{ombox | type=notice | text = Columns are currently supported only by newer versions of [[Gecko (layout engine)|Gecko]]-based browsers (such as [[Mozilla Firefox]]) and [[WebKit]]-based browsers (such as [[Google Chrome]] and [[Safari (web browser)|Safari]]).

This template encapsulates the {{tag|references |single}} tag to show the list of references defined by {{tag|ref}} tags, with some formatting. It reduces the font size and has options for columns and groups. References can be defined within the body of the article or within the reference list.

The {{tag|ref}} and {{tag|references |single}} tags are part of the [[mw:Extension:Cite/Cite.php|Cite.php]] MediaWiki extension.

=== Spalten ===
Using {{tlx|Reflist|2}} will create a two-column reference list, and {{tlx|Reflist|3}} will create a three-column list, and so on. Choose the number of columns that is appropriate for the average width of the references on the page.

Using {{tlx|Reflist|30em}} will create columns with a minimum width of 30 [[Em (typography)|em]], allowing the browser to automatically choose the number of columns based on the width of the web browser. Choose a column width that is appropriate for the average width of the references on the page.

Columns are currently supported only by [[Gecko (layout engine)|Gecko]]-based browsers (such as [[Mozilla Firefox]]) and [[WebKit]]-based browsers (such as [[Google Chrome]] and [[Safari (browser)|Safari]]). See [[#Browser support for columns|below]] for more information.

=== Listenstile ===
{{ombox | type=notice | text='''This is an experimental feature that may be subject to change.'''<br />See [[Wikipedia:Manual of Style (footnotes)/Cite link labels]] for more information. }}
Reference lists are by default numbered lists. By using the <code>liststyle=</code> parameter, you can control how the list is rendered. For example, using <code>liststyle = upper-roman</code> will result in items being prefixed with [[roman numerals]] instead of decimal numbers. The parameter accepts any valid CSS value defined for <code>list-style-type</code> as shown below.

{{CSS list-style-type values}}

=== Mehrfachverwendung ===
If {{tl|Reflist}} is used multiple times without a parameter, each instance will include all of the previously defined references. To force the parser to close previous references, each use of {{tl|Reflist}} must be forced as a new instance by the use of any parameter. Even an undefined parameter such as {{tlx|Reflist|close&#61;1}} will force the references to close.

=== Listen-definierte Referenzen ===
{{see|WP:List-defined references}}
A list of references may be defined within {{tl|Reflist}} using the {{para|refs}} parameter, just like including named <nowiki><ref name=". . ."></nowiki> elements inside the <nowiki><references></nowiki> container. This has been available since September 2009. There are new error messages associated with this feature, documented at [[Help:Cite errors]], including one for references defined in {{tl|Reflist}} but not used within the body.

==== Beispiel ====
<pre>
This is reference 1.<ref name="refname1" />
This is reference 2.<ref name="refname2" />

{{Reflist|refs=
<ref name="refname1">content1</ref>
<ref name="refname2">content2</ref>
}}
</pre>

==== Resultat ====
This is reference 1.<ref name="refname1" group="LDR"/>
This is reference 2.<ref name="refname2" group="LDR"/>

{{Reflist|group="LDR"|refs=
<ref name="refname1">content1</ref>
<ref name="refname2">content2</ref>
}}

The “LDR” group text is to avoid conflicts with other groups of references in this documentation and would not be present in real use.

=== Gruppierte Referenzen ===
As of June 2008, the footnotes system supports the separation of references into groups. This allows groups for explanatory notes, table references and the like. See [[WP:REFGROUP]].

The general format for the reference tag is:

:{{tag|ref|open|params=group=''"groupname"''}}

And using {{para|group}} for the reflist:
:{{tlx|Reflist|2=group=''"groupname"''}}

:Where ''groupname'' would be a group identifier such as "note", "nb" or "label".

There are three pre-defined group names that will automatically cause the link labels and this template to display other characters instead of numbers (see [[#List styles|List styles]] above). These are: "lower-alpha" (a, b, c...), "lower-greek" (α, β, γ...) and "lower-roman" (i, ii, iii...).

== Fontgröße ==
The font size should reduce to 90% for most browsers, but may appear to show at 100% for Internet Explorer and possibly other browsers.<ref name=fontsize/> As of December 21, 2010, the standard {{tag|references|single}} tag has the same font styling. The smaller font may be disabled through [[Special:Preferences]] → Gadgets → Disable smaller font sizes of elements such as Infoboxes, Navboxes and References lists.

=== Browser-Unterstützung für Spalten ===
{{CSS3 multiple column layout}}
Multiple columns are generated by using [[Cascading Style Sheets|CSS3]], which is still in development; thus only browsers that properly support the multi-column property will show multiple columns with {{tl|Reflist}}.<ref name="stuffandnonsense" /><ref name="w3org1" />

Diese Browser '''unterstützen''' CSS3 Spalten:
* [[Gecko (layout engine)|Gecko]]-based browsers such as [[Mozilla Firefox]]
* [[WebKit]]-based browsers such as [[Safari (web browser)|Safari]] and [[Google Chrome]]
* [[Opera (web browser)|Opera]] from version 11.10 onward
* [[Internet Explorer]] 10 Platform Preview

Diese Browser '''unterstützen nicht''' CSS3 Spalten:
* Microsoft [[Trident (layout engine)|Trident]]-based browsers including Internet Explorer through to version 9<ref name=msdn />
* [[Opera (web browser)|Opera]] through to version 11

=== Unterstützung CSS ===
{{tl|reflist}} nutzt eine CSS-Regel in [[MediaWiki:Common.css]], um die Schriftgröße einzustellen:

* <code>div.reflist { font-size: 90%; }</code>

Einer der folgenden Klassen wird durch die Vorlage, wenn entweder die Anzahl der Spalten oder Spaltenbreite zugewiesen ist:

* <code>.references-column-count</code> and <code>.references-column-count-''n''</code> (where <code>''n''</code> is the numer of columns)
* <code>.references-column-width</code>

The following CSS properties are utilized using the {{tl|column-count}} and {{tl|column-width}} templates:

* <code>column-count</code> CSS3 standard
* <code>column-width</code> CSS3 standard
* <code>-moz-column-count</code> Mozilla CSS extension
* <code>-moz-column-width</code> Mozilla CSS extension
* <code>-webkit-column-count</code> Webkit CSS extension
* <code>-webkit-column-width</code> Webkit CSS extension

=== Anpassen der Ansicht ===
{{siehe|Hilfe:Referenz-Anzeige Anpassung}}
By editing your CSS, the personal appearance of the reference list can be customized. From [[Special:Preferences|Preferences]], select the Appearance tab, then on the selected skin select Custom CSS. After editing and saving, follow the instructions at the top of the page to purge. See [[Wikipedia:Skin#Customisation (advanced users)]] for more help.

;Font size
The font size for all reference lists defaults to 90% of the standard size. To change it, add:

<source lang="css">
ol.references,
div.reflist,
div.refbegin {
    font-size: 90%;
}
</source>

Change 90% to the desired size.

;Columns
To disable columns, add:

<source lang="css">
.references-column-count, .references-column-width {
    column-count: 1 !important;
    column-width: auto !important;
    -moz-column-count: 1 !important;
    -moz-column-width: auto !important;
    -webkit-column-count: 1 !important;
    -webkit-column-width: auto !important;
}
</source>

Similarly, to force all reference lists to a number of columns, change the number.

;Column dividers
To add dividers (rules) between columns, add:

<source lang="css">
.references-column-count, .references-column-width {
    column-rule: 1px solid #aaa;
    -moz-column-rule: 1px solid #aaa;
    -webkit-column-rule: 1px solid #aaa;
}
</source>

You can alter the appearance of the dividers by changing the values.

===Bugs===
{{anchor|groupandcolumn}}
Note that, whereas <nowiki>{{reflist|15em|group="e"}}</nowiki> works as expected, <nowiki>{{reflist|15em |group="e"}}</nowiki> (with an extra space) currently does not display in columns.
