How to create recursive elements on a form

[copostic]

Hello,

I have a main element with an Edit screen, let's call it Library.
I would like to add on the LibraryEditScreen a subform to add as many Books (which belongs to a Library) as I want.
And do this logic recursively, for example, once I created my book, I'd like to have a form to create Chapters.

Is there any way to do it ?

I don't know if I'm really clear, otherwise, don't hesitate to ask me to clarify something :)

Thanks a lot guys ! 😄
