{{high-risk}}

== Usage ==

Meta template that returns the first parameter if evaluated during substitution, and the second parameter if evaluated during transclusion.<br />Note that this template must be used in [[mw:Manual:Substitution#Multilevel_substitution|safesubst]] mode to work properly: 

: <code><nowiki>{{ safesubst:<noinclude/>ifsubst| yes | no }}</nowiki></code>



The {{para|demo}} parameter can be used for testing the template. Set {{para|demo|yes}} to always display the ''yes'' text, {{para|demo|no}} to always display the ''no'' text, or {{para|demo|<nowiki>{{{demo|}}}</nowiki>}} to pass through the value from the parent template.
