Hello good day! I will have a function in my wordpess where I will add products used by athletes, and I need to generate these dynamic fields.
In addition to letting type 5 fields available, I would like to put a + sign to whoever is registering the athlete on the site, he add the products he uses. Type if it uses 2 products, click on + 2 times and add 2 fields.
Does ACF have this kind of function?

I’m not entirely sure what you are asking, but the image that you have is a repeater field. https://www.advancedcustomfields.com/resources/repeater/
Hello,
Sorry to resume this topic but i am looking into this as well, repeater does what i need but i have 60000+ posts and they are saved in another format (serialized array), repeater does 1 row for the field + 1 row for each subfield, is there a way to serialize at least the subfields into a single one? Recompiling every post using those fields would be a long and boring task, and some of those fields are API updated and would require a lot of work on that side as well.
I have looked up THIS link and i can’t find any filter / action for repeater (are they considered inbase of the subfields?)
Thanks in advance for the feedback
