Framework-Specific Types

Here are the supported type values that are specific to the framework.

type Example Description
Aura.Component N/A A single component. We recommend using Aura.Component[] instead.
Aura.Component[] <aura:attribute name="detail" type="Aura.Component[]"/>

To set a default value for type="Aura.Component[]", put the default markup in the body of aura:attribute. For example:

1swfobject.registerObject("clippy.codeblock-0", "9");

 Use this type to set blocks of markup. An attribute of type Aura.Component[] is called a facet.
