I want to embed just the order form, but right now the only way to do that is create a funnel with just the order form element and then embed the entire page.

You should make Order Forms an option just like Forms or Surveys... or better yet, when you click Create Form you should choose whether its a lead capture form, order form, etc.

That would give us a lot more flexibility and control over the order form design and elements and greatly increase it's flexibility to drop in other sites (such as wordpress) that we might already have setup.
