<section begin=pregroup /><!--this section is used as the documentation for the efn/notelist templates-->{{anchor|footnotes_predefined_groups}}
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 (superscript lowercase letters like <sup>'''''a b c'''''</sup>) 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}}, which works the same as the parameter in {{tag|ref|o}} (see, for instance, the 4th and 5th examples below). It also supports {{para|group}}, which functions similarly to the parameter of the same name in {{tag|ref|o}} but accepts only 'lower-alpha', 'upper-alpha', 'lower-roman', 'upper-roman', 'lower-greek', or 'note'.  Do not enclose values in quotes.
* {{tlx|notelist}} supports the {{para|colwidth}} and {{para|refs}} parameters, which work the same as the same parameters in {{tlx|reflist}}, and {{para|group}}, which works similarly to the parameter of the same name in {{tlx|efn}}. Do not enclose values in quotes.

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

'''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}}

[[WP:LDR|List-defined footnotes]] are incompatible with Visual Editor. {{tl|notelist}} is a simply a wrapper for {{tl|reflist}}, which is a wrapper for {{tag|references|s}}. Explanatory footnotes can be used with the raw tag (which ''is'' compatible with Visual Editor) by specifying the correct group name, for example:

<pre>
<references group="lower-alpha">
<ref name="name1">Content</ref>
<ref name="name2">Content</ref>
</references>
</pre>

{{tl|refwidth}} can be used to set column widths.
