How to add multiple inline shapes to a model in a tree view (inlines in inline)?

Question

Django

Goal: change the form for creating a survey so that all questions and answers can be asked in one field. I created an inline question, and in it already prepared inside (or under it, but indented, that is, it is clear that they are subordinate) inline answer options.
I hope I was able to convey the idea.
