AvailableContentTypes

There is an additional optional attribute for content types called AvailableContentTypes that can be used to set which content types that should be available under a content instance. The configurable properties for the attribute are displayed below.

Property nameDescriptionDefault value
Availability Defines if all or none content types should be available. If none is set other settings on the attribute is ignored. Availability.All
Include A type array of typed content to specify which content types that should be available under a content instance of the type with the attribute. Type[0]
Exclude A type array of typed content to specify which content types that should not be available under a content instance of the type with the attribute. Type[0]
IncludeOn States that the content with this attribute should be available under the all the typed content in the type array. Type[0]
ExcludeOn States that the content with this attribute should be not available under the any of the typed content in the type array. Type[0]

The types given on Include, Exclude, IncludeOn and ExcludeOn can either be a typed content directly or it can be the type of an interface or a base class. At registration all registered types that can be assigned to the specified type will be included. For example, if an interface is specified in Include list then all typed pages that implement the interface will be included.

IncludeOn differs from Include in the way that it is not excluding. That is for types in IncludeOn that has all content types available no content types will be excluded. Include on the other hand will exclude all typed content except the ones given in Include. Below is an image that shows how Included and IncludeOn are mapped to settings in admin view.

Included

Exclude works so that if no types are set on Included then the result will be that all registered page types except the Exclude ones are available. If there are types registered in Include then all types in Include except the ones in Exclude are available. Below is an image that shows how Exclude and ExcludeOn are mapped to settings in admin view.
