Hello Nick,
WordPress itself saves the array to the database as a serialized string and our plugin works with that standard feature. There are some benefits noted in the documentation https://docs.metabox.io/cloning-fields/#data-of-cloneable-fields
- Works for all field types, including nested groups.
- Works perfectly with the helper function or with WordPress's get_post_meta function (WordPress automatically deserializes string and returns an array).
- Reduces the database size (number of rows), especially when you have nested groups of many fields.
.
