Usage: Semantics: Markup variables with <var>

New page

{{Documentation subpage}}
{{High-use}}
{{Lua|Module:If preview}}

This is a template that helps other templates determine if they are being previewed or not, and do or display different things accordingly.

== Usage ==
<code><nowiki>{{</nowiki>If preview|<var>value if being previewed</var>|<var>value if not being previewed</var><nowiki>}}</nowiki></code>

<code><nowiki>{{</nowiki>If preview|1=<var>value if being previewed</var>|2=<var>value if not being previewed</var><nowiki>}}</nowiki></code>

The first parameter is returned if the page is being previewed, otherwise the second parameter will be returned. Either parameter may be empty.

==Examples==
Preview this page to see the effect of previewing on the 'Example' column.
{|class=wikitable
!Code
