### Create a Datasource for ComboBox

1.  Add a new class to the folder **Models** (for example: `Cities.cs`).
2.  Add the following code to the new model to define the classes that serve as a datasource for the ComboBox control.
    
    ```CITIES
    public class Cities
    {
        public static List<string> GetCities()
        {
            return new List<string>
            {
                "Abidjan", "Accra", "Ahmedabad", "Alexandria", "Ankara", "Atlanta", "Baghdad", "Bandung", "Bangkok", "Barcelona", "Beijing", "Belo Horizonte",

    ```csharp
    public IActionResult Index()
    {
        return View();
