There are several predefined groups that can have a reference list styled so that the label (a superscripted character within square brackets, e.g., {{dummy ref|1}}) of an [[Help:Explanatory notes|explanatory note]] or citation (aka footnote, reference) matches and links to the note marker label located in the main text and the label in front of the note's text in the appropriate group's list. There can be [[Wikipedia:Citing sources#Separating citations from explanatory footnotes|more than one of these groups' lists]] in the Notes, References and other similarly purposed sections.

These predefined note and citation groups have templates that make the [[wikitext]] markup simpler. These templates also allow a standard reference to be inserted, so that an explanatory note can have a reference, or citations can be nested.

'''Note:''' If the note's text has a reference name that is used more than once, the labels will still match, but the clickable alpha characters that toggle the note's display will be ''next to'' the note's label, with links to the multiple locations of its marker in the main text. See [[Help:Footnotes#Footnotes: using a source more than once|WP:REFNAME]] and the first point below in [[#Issues|§&nbsp;Issues]].

* {{tlx|efn}} supports {{para|name}} and {{para|group}}, which work the same as the parameters in {{tag|ref|o}} (see, for instance, the 3rd and 4th examples below). Do not enclose values in quotes.
* {{tlx|notelist}} supports the {{para|colwidth}}, {{para|refs}}, and {{para|group}} parameters, which work the same as the parameters in {{tlx|reflist}}. Do not enclose values in quotes.

In these examples, the footnote labels match between the footnote marker and the reference list:

{{markup|title=With lower-alpha labels
|<nowiki>Lorem ipsum dolor sit amet.{{efn|Footnote 1}} Consectetur adipisicing elit.{{efn|Footnote 2}} Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.{{efn|Footnote 3}}

{{notelist}}
</nowiki>
|Lorem ipsum dolor sit amet.{{efn|Footnote 1}} Consectetur adipisicing elit.{{efn|Footnote 2}} Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.{{efn|Footnote 3}}

{{notelist}}
}}

{{markup|title=With lower-roman labels
|<nowiki>Lorem ipsum dolor sit amet.{{efn-lr|Footnote 1}} Consectetur adipisicing elit.{{efn-lr|Footnote 2}} Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.{{efn-lr|Footnote 3}}

{{notelist-lr}}
</nowiki>
|Lorem ipsum dolor sit amet.{{efn-lr|Footnote 1}} Consectetur adipisicing elit.{{efn-lr|Footnote 2}} Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.{{efn-lr|Footnote 3}}
{{notelist-lr}}
}}

{{markup|title=With named references
|<nowiki>Lorem ipsum dolor sit amet.{{efn|name=fn1|Footnote 1}} Consectetur adipisicing elit.{{efn|Footnote 2}} Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.{{efn|name=fn1}}

{{notelist}}
</nowiki>
|Lorem ipsum dolor sit amet.{{efn|name=fn1|Footnote 1}} Consectetur adipisicing elit.{{efn|Footnote 2}} Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.{{efn|name=fn1}}
{{notelist}}
}}
Note: With named references you only need to add the details once. For each use after the first you just need to re-use the reference name. Doing this will not cause the inline superscript to display a custom name.

{{markup|title=Named references can also be defined in the notelist
|<nowiki>Lorem ipsum dolor sit amet.{{efn|name=fn1}} Consectetur adipisicing elit.{{efn|name=fn2}} Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.{{efn|name=fn1}}

{{notelist|refs=
{{efn|name=fn1|Very long footnote 1}}
{{efn|name=fn2|Very long footnote 2}}
}}
</nowiki>
|Lorem ipsum dolor sit amet.{{efn|name=fn1}} Consectetur adipisicing elit.{{efn|name=fn2}} Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.{{efn|name=fn1}}
{{notelist|refs=
{{efn|name=fn1|Very long footnote 1}}
{{efn|name=fn2|Very long footnote 2}}
}}
}}
'''Note''': Due to limitations in the MediaWiki software, do not use list defined footnotes that contain references. 

===Issues===
* Multiple backlink labels (see [[WP:REFNAME]]) are always styled as lower-alpha. This can be confusing when {{tlx|efn}} is used. See the note in the introduction of [[#footnotes_predefined_groups|this section]], above.
* The entries in the reference list will show the default decimal styling if:
** The value for {{para|group}} in {{tlx|reflist}} or {{tag|references|s}} does not exactly match one of the predefined values; use {{tlx|efn}} or variant as {{para|group}} will not be needed.
** The value for {{para|group}} in {{tlx|reflist}} or {{tag|references|s}} is enclosed by quotes; use {{tlx|efn}} or variant as {{para|group}} will not be needed.
** {{tlx|reflist}} is indented with the {{code|:}} markup.
** {{tag|references|s}} is used instead of {{tlx|reflist}}
* The entries in the reference list will have no styling if:
** A reference is included in {{tlx|navbox}} or one of the variants and the style is set to <code>bodyclass=hlist</code>; to resolve this, replace the style with <code>listclass=hlist</code>.<section end=pregroup />
* If the note text contains an "=" sign, precede the note text with {{para|1}}, like this: <code><nowiki>{{efn|name=fn1|1=Very long footnote with an equation, 2+2=4}}</nowiki></code>
