Introduction
You can incorporate the content of one tiddler within another using the Transclusion notation:
{{MyTiddler}}
transcludes a single tiddler{{MyTiddler||TemplateTitle}}
displays the tiddler through a specified TemplateTiddler{{||TemplateTitle}}
displays the specified template tiddler without altering the current tiddler{{MyTiddler|Parameter}}
transcludes a single tiddler with a single parameter{{MyTiddler||TemplateTitle|Parameter|SecondParameter}}
transcludes a single tiddler through a specified TemplateTiddler with two parameters
Transcluding Text References
You can also use a TextReference instead of a tiddler title:
{{MyTiddler!!field}}
transcludes a specified field of a tiddler{{!!field}}
transcludes a specified field of the current tiddler{{MyTiddler##index}}
transcludes a specified indexed property of a DataTiddler{{##index}}
transcludes a specified indexed property of the current DataTiddler
Filtered Transclusion
A similar syntax can be used to generate or transclude a list of tiddlers matching a specified filter:
{{{ [tag[mechanism]] }}}
{{{ [tag[mechanism]]||TemplateTitle }}}
In contrast to Filtered Attribute Values, all items matching the filter are transcluded and not only the first.
Generated Widgets
The WikiText transclusion syntax generates a TiddlerWidget wrapped around a TranscludeWidget. For example, {{MyTiddler||TemplateTitle}}
generates the following pair of widgets:
<$tiddler tiddler="MyTiddler">
<$transclude $tiddler="TemplateTitle"/>
</$tiddler>
The filtered transclusion syntax {{{ [tag[mechanism]] }}}
generates the following widgets
<$list filter="[tag[mechanism]]">
<$link />
</$list>
or, when used with a template, {{{ [tag[mechanism]]||TemplateTitle }}}
expands to
<$list filter="[tag[mechanism]]">
<$transclude tiddler="TemplateTitle" />
</$list>
