Serialize inherited List class, to display in Inspector

I am creating a custom class based on List and want to set it so that it displays in the inspector just like an ordinary List would.

 public class CimManager : MonoBehaviour {
     [System.Serializable]
     public class CimList : List<string>
         {
         //some methods and accessors here, but no variables
         }
 }

in another Monobehaviour:

 public class TenantClass : MonoBehaviour {
         public CimManager.CimList occupants = new CimManager.CimList();
 }

I have TenantClass attached to a GameObject, and when inspecting the GameObject I see the Occupants field in the inspector, but there is no option to choose its length nor is there a dropdown arrow to expand the list to enter in my own values. This is also the case when I know that the CimList already is populated.

Screenshot

I want it to display the way Rates does (which is a float[] )

I know one workaround is to define TenantClass.occupants as a standard List and cast it to my CimList class whenever I need the extra functions, but is there a more proper way of doing this?

try use


[SerializeField]
private List occupants = new List();
public CimManager.CimList Occupants { get { return new CimManager.CimList (occupants); }  }

An use "Occupants" not "occupants" in your code after use do this:

 ocupants.Clear();
 ocupants.AddRange(Ocupants);

I can't do this because getting Ocupants returns a new instance of the occupants list. I need to be able to access it directly. Doing things like Occupants.Add(newOccupant) doesn't affect the private occupants list. This is really work-around-y anyway, I am more looking for more documentation regarding serialization for unity inspector so I can do it properly.

Can you use a standtard list and create Extension methods for the list class
