 ## List of structs
 
 As was discussed in the earlier available choices. In the `field` macro that is used to call **another module**, as well as in the `sub_field` macro, you have the ability to retrieve a list of structs rather than a single struct.

 > **Note**: When changing a record in the database, for example, you might need to make sure that a particular piece of data does not get overwritten by an automatic piece of data if one already exists.

 ## From core key
 
 You can select this alternative if you require any data that was delivered in another key to be incorporated into the key that you are looking for. If the key is present, the data associated with it will be copied; however, if the key is not there, the data in and of itself will be retained.

 ## Domain core key
 
 When dealing with a structure that is heavily nested, it is occasionally necessary to establish the permitted range of values for a set of parameters based on the input provided by a parent.

 ## Conditional fields
 
 One of the unique capabilities of this macro is the ability to define conditions and differentiate between the various kinds of `fields`. Assume that you want the `social` field to be able to take both a value `string` and a `map` where `address` and `provider` are included in the `map`.
