Template documentation[view] [edit] [history] [purge]

There are several predefined groups that can have a styled reference list such that the footnote labels match between the footnote marker and the footnote in the reference list. These predefined groups and reference lists have templates that make the markup simpler and also allow a standard reference to be inserted, so that an explanatory note can have a reference.

Group name	Footnote marker template or markup	Reference list template	Sample labels
none	`<ref>...</ref>`	`{{reflist}}`	1 2 3 4 5 6 7 8 9 10
none	`{{refn}}` for nested references	`{{reflist}}`	1 2 3 4 5 6 7 8 9 10
lower-alpha	`{{efn}}`	`{{notelist}}`	a b c d e f g h i j
upper-alpha	`{{efn-ua}}`	`{{notelist-ua}}`	A B C D E F G H I J
lower-roman	`{{efn-lr}}`	`{{notelist-lr}}`	i ii iii iv v vi vii viii ix x
upper-roman	`{{efn-ur}}`	`{{notelist-ur}}`	I II III IV V VI VII VIII IX X
lower-greek^{[lower-alpha 1]}	`{{efn-lg}}`	`{{notelist-lg}}`	α β γ δ ε ζ η θ ι κ

{{efn}} supports |name= and |group=, which work the same as the parameters in <ref>. Do not enclose values in quotes.
{{notelist}} supports the column parameter, |refs= and |group= which work the same as the parameters in {{reflist}}. Do not enclose values in quotes.

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

**With lower-alpha labels**

{{notelist-lr}}

Lorem ipsum dolor sit amet.^{[lower-roman 1]} Consectetur adipisicing elit.^{[lower-roman 2]} Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.^{[lower-roman 3]}

**With named references**

With named references, the references are defined in the notelist

{{efn|name=fn1|Very long footnote 1}}
{{efn|name=fn2|Very long footnote 2}}
}}

Lorem ipsum dolor sit amet.^{[lower-alpha 5]} Consectetur adipisicing elit.^{[lower-alpha 7]} Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.^{[lower-alpha 5]}

Issues

Multiple backlink labels are always styled as lower-alpha. This can be confusing when {{efn}} is used.
The entries in the reference list will show the default decimal styling if:
- The value for |group= in {{reflist}} or <references /> does not exactly match one of the predefined values; use {{efn}} or variant as |group= will not be needed.
- The value for |group= in {{reflist}} or <references /> is enclosed by quotes; use {{efn}} or variant as |group= will not be needed.
- {{reflist}} is indented with the : markup.
- <references /> is used instead of {{reflist}}
The entries in the reference list will have no styling if:
- A reference is included in {{navbox}} or one of the variants and the style is set to bodyclass=hlist; to resolve this, replace the style with listclass=hlist.
Including external link markup will result in an error. Use the {{URL}} template instead: {{URL|1=url name|2=optional display text}}.

Example articles

Logic Theorist (a short article showing basic usage)
Chinese room (a long and complex article which uses all the features: named footnotes, list defined notes, etc.)
Empire of Brazil
John Diefenbaker (with name= and notes in {{notes}})
USS Monitor
