How to Set Up an Infobox

Follow these steps, if you'd like to set up an infobox that displays only those attributes that have a value — all other attributes are omitted.

Step by Step

Create an infobox template where the code for all optional attributes (those that a user might want to exclude) is surrounded by

• “[!--{$attribYes}-]” (where attrib is any infobox attribute name) and
• “[!-- --]”,

for example:

[[table]]
[[row]]
[[cell]]**Name:**[[/cell]][[cell]]{$name}[[/cell]]
[[/row]]
[!--{$playerYes}-][[row]]
[[cell]]**Player:**[[/cell]][[cell]]{$player}[[/cell]]
[[/row]][!-- --]
[!--{$originYes}-][[row]]
[[cell]]**Origin:**[[/cell]][[cell]]{$origin}[[/cell]]
[[/row]][!-- --]
[[/table]]

Note:
The template should not contain any Wikidot comments ([!-- … --]) within the source code of an optional block (except the ones needed for the above structure)

On your including page, if you want to have an attribute appear, specify

attribYes=- | attrib=value-of-this-attribute

on the [[include infobox-template-name …]] tag.

Attributes that are not listed on the [[include …]] tag, are not displayed.

This also means, that you can at a later time change the infobox template (e. g. add another optional attribute) without breaking all existing includes.

Examples

 [[include infobox name=Its name
| playerYes=- | player=a player
| originYes=- | origin=The origin of this thing
]]

 [[include infobox name=Its name]]
]]
