Custom page property

Hello,

So I am trying to get a custom page property set in the admin panel. The structure shold be like this class

    public class Indexer
    {
        public string name { get; set; }
        public List<Lookup> options { get; set; } = new List<Lookup>();
    }

So when I go to editor I want to see something like

Continent      List of continent

Regions        List of regions

I am trying to create custom properties but haven't had any success as of yet. Do you guys think that this is something that could be done?
