I am looking for a solution for the following situation:
I have an offer structure as follows (same for the live environment):
Offer Category A (parent)
Offer Category B
Now I want to create a form in the delivery-forms that gives me a dynamic drop down list, where I can choose all sub-categories from Offer Category A for example (Sub A, Sub B).
I want this list to be extended automatically, when a new sub-categorie in Offer Category A (parent) is created.
I hope my explanation is detailled enough.
