{{lua|Module:Labelled list hatnote}}

This template is used to create '''[[WP:Hatnotes|hatnotes]] to point to a small number of other related titles''' at the '''top of article ''[[Help:Section|sections]]''''' (excluding the [[WP:LEAD|lead]]). It looks like this:

{{See also|Wikipedia:Article title}}

Do not use this template on top of a page, where hatnotes are for disambiguation and not for related topics (according to [[WP:RELATED]]). Do not use this template inside [[Wikipedia:Manual of Style/Layout#"See also" section|the ''"See also" section'']] at the end of an article, or for links to other articles or subsections of the same article within regular article text. Where subsections are linked to, [[Template:Section link]] may be suitable instead. For use on category pages, the corresponding template is [[Template:Category see also]].

Refer to the examples below to see how the template handles link targets containing section links and commas.

==Usage==
{{see|WP:SUMMARYHATNOTE}}
; Basic usage:
 &#123;{See also|''page1''|''page2''|''page3''|...}}

; All parameters:
 &#123;{See also|''page1''|''page2''|''page3''| ...
 |label 1 = ''label 1''|label 2 = ''label2''|label 3 = ''label3''| ...
 |l1 = ''label1''|l2 = ''label2''|l3 = ''label3''| ...
 |selfref = ''yes''|category = ''no''}}

==Parameters==
This template accepts the following parameters:
* {{para|1}}, {{para|2}}, {{para|3}}, ... – the pages to link to. At least one page name is required. Categories and files are automatically escaped with the [[Help:Colon trick|colon trick]], and links to sections are automatically formatted as ''page § section'', rather than the MediaWiki default of ''page#section''.
* {{para|label 1}}, {{para|label 2}}, {{para|label 3}}, ...; or {{para|l1}}, {{para|l2}}, {{para|l3}}, ...; optional labels for each of the pages to link to.
* {{para|selfref}} – if set to {{pval|yes}}, {{pval|y}}, {{pval|true}}, or {{pval|1}}, adds the CSS class <code>selfref</code>. This is used to denote self-references to Wikipedia. See [[Template:Selfref]] for more information.
* {{para|category}} – if set to {{pval|no}}, {{pval|n}}, {{pval|false}}, or {{pval|0}}, suppresses the error tracking category ([[:Category:Hatnote templates with errors]]). This only has an effect if the first positional parameter (the page to link to) is omitted.

== Examples ==

{{nowiki template demo|format=inline|code=<nowiki>{{See also|Article}}</nowiki>}}
{{nowiki template demo|format=inline|code=<nowiki>{{See also|Article#Section}}</nowiki>}}
{{nowiki template demo|format=inline|code=<nowiki>{{See also|Article#Section|label 1=Custom section label}}</nowiki>}}
{{nowiki template demo|format=inline|code=<nowiki>{{See also|Article1|Article2|Article3}}</nowiki>}}
{{nowiki template demo|format=inline|code=<nowiki>{{See also|Article1|l1=Custom label 1|Article2|l2=Custom label 2}}</nowiki>}}
{{nowiki template demo|format=inline|code=<nowiki>{{See also|Veni, vidi, vici|Julius Caesar}}</nowiki>}}
{{nowiki template demo|format=inline|code=<nowiki>{{See also|Veni, vidi, vici|Julius Caesar#Civil war}}</nowiki>}}
{{nowiki template demo|format=inline|code=<nowiki>{{See also|Julius Caesar#Civil war|Veni, vidi, vici}}</nowiki>}}
{{nowiki template demo|format=inline|code=<nowiki>{{See also|Julius Caesar#Civil war|Crossing the Rubicon}}</nowiki>}}

==Errors==
If no page names are supplied, the template outputs the following message with the (help) wikilink pointing to the "Errors" section of this page: 
*{{See also|category=no}}

If you see this error message, it is for one of three reasons:
# No parameters were specified (the template code was <code><nowiki>{{See also}}</nowiki></code> with no pipe character nor page to link to). Please use <code><nowiki>{{See also|</nowiki>''page''<nowiki>}}</nowiki></code> instead.
# Some parameters were specified, but no page names were included. For example, the template text <code><nowiki>{{See also|selfref=yes}}</nowiki></code> will produce this error. Please use (for example) <code><nowiki>{{See also|</nowiki>''page''<nowiki>|selfref=yes}}</nowiki></code> instead.
# A page name was specified, but it contains an equals sign ("="). The equals sign has a special meaning in template code, and because of this it cannot be used in template parameters that do not specify a parameter name. For example, the template code <code><nowiki>{{See also|1+1=2|2+2=4}}</nowiki></code> will produce this error. To work around this, you can specify the parameter name explicitly by using <code>1=</code>, <code>2</code>, etc., before the page name, like this: <code><nowiki>{{See also|1=1+1=2|2=2+2=4}}</nowiki></code>.

If you see this error message and are unsure of what to do, please post a message on [[WP:HD|the help desk (WP:HD)]], and someone should be able to help you.
