ASP.NET MVC / DDD architecture support

I am creating a web application using ASP.NET MVC and I am trying to use domain driven design. I have an architecture question.

I have a WebControl table to store keys and values ​​for lists so that they can be editable. I have incorporated this into my business model, but it results in a lot of redundant code and I'm not sure if it is there. For example, in my Request class, I have a property called NeedType. Since this comes from a list, I created a NeedType class to provide values ​​for the radio buttons. I'm only showing one example here, but the form will probably have a dozen lists that should come from the database.

[edit to clarify the question] What's the best way to do this? Are these list objects really part of my domain, or are they just for the UI? If it's not part of a domain, then they don't belong to my main project, so where do they go?

public class Request : DomainObject
{
   public virtual int RequestId { get; set; }
   public virtual DateTime SubmissionDate { get; set; }
   public virtual string NeedType { get; set; }
   public virtual string NeedDescription { get; set; }
   // etc.
}

public class NeedType : DomainObject
{
    public virtual int NeedTypeId { get; set; }
    public virtual string NeedTypeCode { get; set; }
    public virtual string NeedTypeName { get; set; }
    public virtual int DisplayOrder { get; set; }
    public virtual bool Active { get; set; }
}

public class RequestController : Controller
{
    private readonly IRequestRepository repository;

    public RequestController()
    {
        repository = new RequestRepository(new HybridSessionBuilder());
    }

    public RequestController(IRequestRepository repository)
    {
        this.repository = repository;
    }

    public ViewResult Index(RequestForm form)
    {
        ViewData.Add("NeedTypes", GetNeedTypes());
        if (form == null)
        {
            form = new RequestForm();
            form.BindTo(repository.GetById(125));
        }
    }

    private NeedType[] GetNeedTypes()
    {
        INeedTypeRepository repo = new NeedTypeRepository(new HybridSessionBuilder());
        return repo.GetAll();
    }
}
