Insert Multiple records from ViewModel in ASP.Net MVC

I'm making a MVC Application & i want to ask how to insert multiple record on a table from single view.

In My Model there are tables like Customer,Login,CustomerData and etc.

Only CustomerData Tables are having Multiple rows other tables are single rows at single time.

Below is my Code Section.

From this Code i can get the single/First row in Customerdata but i want this to modified for multiple Rows insert in CustomerData.

Any Help would be appreciated.

Thanks.

View Model:

    public class MultipleModel
    {
        public Customer Customer { get; set; }
        public CustomerData CustomerData { get; set; }
        public SalesMan SalesMan { get; set; }
        public Login Login { get; set; }
        public AccountMaster AccountMaster { get; set; }
        public CustomerProgress CustomerProgress { get; set; }
        public CustomerStatu CustomerStatus { get; set; }
        public List<CustomerData> CData { get; set;}
    }

 Razor:

@model SerbaantikCRM.Models.MultipleModel

FYI In This View there are other Controls in which I'm using other model (like Salesman and Customer and etc)
