This template simply places template code in a <syntaxhighlight lang="wikitext">...</syntaxhighlight> tag and then places the template below the code.

{{demo
|br =
|demo_kill_categories =
|<nowiki>{{your template}}</nowiki>
}}

IMPORTANT: You must wrap include <nowiki>...</nowiki> tags around the source to be demonstrated (or use {{escape}}, which has a demo-escape example), like so:

{{demo|<nowiki>[template source]</nowiki>}}

Failure to wrap <nowiki>...</nowiki> tags around the source may cause the source to be executed before it reaches this template:

{{demo|{{fail}}}}

produces

<big style="color:#DF0A24; font-size:1.4em;"></big> '''Fail'''


 Fail

HTML tags don't work in {{demo}} as well:

<small><b>test</b></small>

is shown as <small><b>test</b></small>

Set |style= to add any CSS text to the <pre>...</pre> tag.

For example,

{{demo|style=margin-left: 1.6em;|<nowiki>{{done}}</nowiki>}}

will produce

{{done}}


ਕਰ ਦਿੱਤਾ

Line breaks

ਸੋਧੋ

You can change the number of line breaks between the pre tag and the template by setting |br= to a number. The default is 1.

{{demo|br=3|&lt;nowiki>{{done}}</nowiki>}}
{{done}}






ਕਰ ਦਿੱਤਾ


Alternative separator

ਸੋਧੋ

You may also include an alternative separator by setting |br= to something other than a number and it will take the place of the br tags. For example, |br=<td> can make demo fit in a table:

{{done}}
ਕਰ ਦਿੱਤਾ


Category removal

ਸੋਧੋ

For templates that add categories (e.g. {{Asbox}}), set |demo_kill_categories= (or |nocat=) to anything to prevent them from showing up in the output:

{{Asbox
| image = Østfold_våpen.svg
| pix = 30
| subject = [[Østfold]] location
| name = Template:Østfold-geo-stub
| category = Østfold geography stubs
| tempsort = *
}}

produces:


If the template used is based on Lua, you can pass args directly to the demonstrated module by invoking Module:Demo like so: (this would reduce server stress)

{{#invoke:Demo|module|demo_br=0| demo_module=RoundN | demo_module_func = N2|demo_template = Round2
|bold_winner=high
|May 1|Team A|1|Team B|2
}}
{{Round2
|bold_winner=high
|May 1|Team A|1|Team B|2
}}
 
Final
 
  
 
May 1
 
 
Team A1
 
 
Team B2
 

Note: It will attempt to preserve line breaks for unnamed params, but such is impossible for named params since those are stripped of whitespace/order before being passed to the module. Also note, you should use |demo_br= instead of |br= (all args you don't want being passed should be prefixed with 'demo_' if not already)
