Сохраните несколько полей с помощью ACF в Woocommerce (корзина, заказ, детали заказа)

Question

Я настраиваю ACF для выбора параметров на странице отдельного продукта. Я уже добавил пользовательские поля на одной странице продукта. Как я могу сохранить несколько полей? Этот код работает, но мне нужно сохранить несколько полей, как в добавленном поле option-color.
