{{tl|Parameter names example}}&nbsp;– or, alternatively, {{tl|Generic template demo}}&nbsp;– is intended to assist template documentation by producing a generic instance of the template that uses [[Help:Templates#Parameters|parameters' names]] as those parameters' values.
{{clear}}

==Example==
The example opposite for {{tl|Infobox}}, for instance, was produced by:

{{Parameter names example |_template=Infobox |title |above |subheader |subheader2 |image |caption |header1 |label2 |data2 |label3 |data3 |header4 |data5 |data6 |below}}

<pre style="overflow:auto;">
{{Parameter names example
|_template=Infobox
|title |above |subheader |subheader2 |image |caption 
|header1 |label2 |data2 |label3 |data3 |header4 
|data5 |data6 |below
}}
</pre>

==Usage notes==
When {{tlf|Parameter names example}} is used on an immediate subpage of its target template&nbsp;– e.g. on the target template's /doc page&nbsp;– its own {{para|_template}} parameter identifying the target template may be omitted. In other words, the code above, if used on Template:Infobox/''page'' (where ''page'' could be "doc", "testcases", etc.), would become:

<pre style="overflow:auto;">
{{Parameter names example
|title |above |subheader |subheader2 |image |caption 
|header1 |label2 |data2 |label3 |data3 |header4 
|data5 |data6 |below
}}
</pre>

One exception to this is the "sandbox" subpage. If the module is called from a page ending in "/sandbox", it uses that page to generate the template output, not the base page. To override this behaviour you can specify the {{para|_template}} parameter explicitly.

The formatting of the parameter names can be changed with the {{para|_display}} parameter. By default, the parameter names are shown in triple braces (the parameter standard, e.g. {{{name}}}{{thin space}}), but if {{para|_display|italics}} or {{para|_display|italic}} is set, they are shown in italics.

A custom value for a parameter may be supplied by using {{para|[parameter name]|[value]}} in place of <code>|[parameter name]</code>. Any formatting for such a value&nbsp;– including, for instance, italics&nbsp;– must be supplied as part of the value (e.g. {{para|parameter|<nowiki>''value''<br/></nowiki>}}). Custom values cannot be used for parameters whose names begin with an underscore ("_").
