What happens when I add a template to a study?

The children of templates are treated like regular study objects unless they are also marked as templates. For example, if you add a codelist template from a library to two different items in another library, the codelist items are links as long as they are not marked as templates.

You can add study objects to a study template using the Libraries tab. If you copy a study object from a library to a study template and then create a study from the study template, the study objects in the study are linked to the original study objects in the library.
