Specify the type of item that you want to display in this slot. When you set up a repository, you define the various item types that it can contain. The setting is important here because a slot can contain items of one type only.

When you add a slot element to a scenario, the ACC presents a menu showing all the items of this type from the repository you specify for the Content Source (see above).

This option corresponds to itemDescriptorName (property of type String) in the slot component .properties file.
