How to to render a webform (or any configurable form) in a node edit form? I have a weird use case, where I was looking to perform the following:


In a node edit form, allow a user to entity reference a collection of webforms
When a user selects an appropriate webform from the entity reference autocomplete, render that form in the current node edit form
User fills out fields in these webforms then proceeds to save the node.
On node save, the webform submit data is stored in a particular field in the node (perhaps in json format).


Is this even possible with webforms, or do any other form modules exist that support this use case?
In this instance it sounds like the paragraphs module solves your problem. However to answer your original question...

I would use entityform, not webform to do this.

Once you added all of your field to your entity form then you can use Inline Entity Form to embed the child form.
