Editing Help:Transclusion (section)

====Hatnote on the target page====
To indicate on the {{em|target page}} where selectively transcluded content originates (its source), a {{tlx|Transcluded section}} [[Wikipedia:Hatnote|hatnote]] must be placed at the top of the corresponding section in the {{em|target page}} where the content is being transcluded {{em|to}}.{{refn|group=lower-alpha|No hatnote should be placed on the {{em|source page}}, in other words no hatnote is needed on the page being transcluded {{em|from}}, as readers do not need to know where else the content appears.}}{{refn|group=lower-alpha|That is the hatnote should be placed below the header but above the content, per [[MOS:Layout]].}} Use either of the following, depending on whether the transcluded content is the entire section or only part of it:
* If an entire section in the target page is transcluded the source: <syntaxhighlight lang="wikitext" inline>{{transcluded section|source=PAGENAME#SECTION}}</syntaxhighlight>, which renders as:
:{{transcluded section|source=PAGENAME#SECTION}}
* If only part of a section in the target page is transcluded the source, specify {{para|part|yes}}: <syntaxhighlight lang="wikitext" inline>{{transcluded section|source=PAGENAME#SECTION|part=yes}}</syntaxhighlight>, which renders as:
:{{transcluded section|source=PAGENAME#SECTION|part=yes}}
