Editing Template:Namespace/doc (section)

== Usage ==

This template takes one or more parameters named after the different page types as listed above. Like this:
<pre>
{{Namespace
 | main  = Article text
 | talk  = Talk page text
 | other = Other pages text
}}
</pre>

If the template is on a main (article) page, it will return this:
: {{Namespace |demospace=main
   | main  = Article text
   | talk  = Talk page text
   | other = Other pages text
  }}

If the template is on any other page than an article or a talk page, it will return this:
: {{Namespace
   | main  = Article text
   | talk  = Talk page text
   | other = Other pages text
  }}

The example above made the template return something for all page types. But if we don't use the '''other''' parameter or leave it empty, it will not return anything for the other page types. Like this:
<pre>
{{Namespace
 | file     = File page text
 | category = Category page text
 | other    =
}}
</pre>

On any pages other than file and category pages the code above will render nothing.
<!-- Do not remove this one. It is supposed to render nothing, but we have it here for testing purposes. -->
: {{Namespace
   | file     = File page text
   | category = Category page text
   | other    =
  }}

By using an empty parameter, you can make it so the template doesn't render anything for some specific page type. Like this:
<pre>
{{Namespace
 | main  = 
 | other = Other pages text
}}
</pre>

The code above will render nothing when on mainspace (article) pages, but will return this when on other pages:
: {{Namespace
   | main  = 
   | other = Other pages text
  }}
