If its embedded then the UI will never be nested and is not customizable. In fact embeddable forums are not actually meant to be treated like a forum as you can see in the UI. They were a way in older versions to provide external commenting. There are now several options to incorporate similar functionality from a pure REST perspective to a REST/widget solution using the scripted endpoint. I highly recommend using one of these methods
Scripting REST Endpoints

Using either REST option does the UI on the external website look like an actual forum? Do you have any clients that you know are using this?
