 | This template is used on approximately 2,400 pages and changes may be widely noticed. Test changes in the template's /sandboxor/testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them. |
 | This template uses Lua:

{{Parameter names example}} – or, alternatively, {{Generic template demo}} – is intended to assist template documentation by producing a generic instance of the template that uses parameters' names as those parameters' values.
An example wikitext to produce a demo for {{Infobox}} (on the right):
| {{{above}}} | |
|---|---|
| {{{subheader}}} | |
| {{{subheader2}}} | |
| {{{image}}}
{{{caption}}}
| |
| {{{header1}}} | |
| {{{label2}}} | {{{data2}}} |
| {{{label3}}} | {{{data3}}} |
| {{{header4}}} | |
| {{{data5}}} | |
| {{{data6}}} | |
| {{{below}}} | |
{{Parameter names example
|_template=Infobox
|title |above |subheader |subheader2 |image |caption
|header1 |label2 |data2 |label3 |data3 |header4
|data5 |data6 |below
}}
When {{Parameter names example}} is used on an immediate subpage of its target template – e.g. on the target template's /doc page – its own |_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:
{{Parameter names example
|title |above |subheader |subheader2 |image |caption
|header1 |label2 |data2 |label3 |data3 |header4
|data5 |data6 |below
}}
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 |_template= parameter explicitly.
The formatting of the parameter names can be changed with the |_display= parameter. By default, the parameter names are shown in triple braces (the parameter standard, e.g. {{{name}}} ), but if |_display=italicsor|_display=italic is set, they are shown in italics.
A custom value for a parameter may be supplied by using |[parameter name]=[value] in place of |[parameter name]. Any formatting for such a value – including, for instance, italics – must be supplied as part of the value (e.g. |parameter=''value''<br/>). Custom values cannot be used for parameters whose names begin with an underscore ("_").
