Is there a way to nested form flow?

[michalpruszynski]

I need to make 3 step flow, but in every step it get another 3 steps. So,
Step1:
step1.1
step1.2
step1.3
Step2:
step2.1
step2.2
...

Is this possible?

No, nested flows aren't supported.

refs #111, #265

Okay, thanks @craue for quick reply.

I've found weird thing with adding a collection type with 'allow_add'.

When im adding a {{ form_row(form.answer.vars.prototype) }} in twig it renders fine, but when i want to use back button - it renders another time, so i've got fields from step 1 and the same fields from step 1 but empty.

When im not calling vars.prototype in twig it doesn't show any field and dumping form returns 0 children.

How is this possible?
