I'm trying to create a "data type" that will allow a content creator to "include" existing content in a new "page". I can create a data type that includes a content picker which can be included in a block list, but I'm not sure what's next.

• If I create a view, does it go under the partials folder?
• How do I include the actual content chosen from the picker in the new element?

Any help would be greatly appreciated.
