Config : Symfony 6.1, PHP 8.1.4, Xampp
I have 3 entities: Carousel, Picture and CarouselPicture.
CarouselPicture is the entity created to make a join table in the ManyToMany relationship with attribute that exists between Carousel and Picture. For each entity there is a FormType.
In my CarouselType (the form for Carousel), I would like to dynamically add fields from CarouselPictureType.
After reading the docs, I understand that you can add a CollectionType... except I can't get it to work.
I probably missed something somewhere but I can't find it.
What I did (cf CarouselType) does not return an error but does not create the fields in question as can be seen below : https://i.stack.imgur.com/g0PUT.png
