Get Parent Form Context from Child Form
Nested Form fields fetch the child form markup via an AJAX request after the parent form has loaded. This
means that when loading child form markup, the child form’s context is not the same as the parent’s. However,
most of the parent form context can be retrieved via the gpnf_context parameter passed in the AJAX request.
Here is an example where we fetch the “my_id” query parameter that was set on the page on which the parent form was loaded.
