Material objects

[NKPmedia]

As a logged in user with the role "ROLE_elder" I want to be able to add a material object.
I want to be able to set:

• name
• a description
• the offers

Every material object must have min. 3 offers.

A offer consists of:

• name
• URL to the offer
• price
• shop name

I want to be able to set the offers while adding the material object.
The material object should be reusable in different material requests.

I want that only I and a user with the role "ROLE_REMOVE_ALL_MATERIAL_OBJECTS"
is able to remove my object. (symfony ACL)
Also only users with the group "ROLE-elder" should be able to see the material object.

symfony collection for offers:
https://symfony.com/doc/current/form/form_collections.html
https://symfony.com/doc/current/reference/forms/types/collection.html

connection between material and offers in MaterialOffers.MaterialId or in material.offers (array of collection) ? (change Doctrine entity)
