Hi You can implement cascading dropdown lists along with manual entry options in your ASP.NET MVC application. You can use JavaScript/jQuery for the cascading dropdown behavior and handle manual entry through text inputs. Here's a high-level overview of the steps involved: Implement cascading dropdown lists for Country State and City using JavaScript/jQuery to fetch data dynamically based on the user's selection. Add manual entry options for each dropdown where users can type their address if the desired option is not available. Handle the manual entry submission and store the values in the database using ASP.NET MVC controllers and models. // Controller Action to fetch States based on selected Country public JsonResult GetStates(int countryId) { var states = db.States.Where(s => s.CountryId == countryId).ToList(); return Json(states JsonRequestBehavior.AllowGet); } // View code for cascading dropdown lists @Html.DropDownListFor(model => model.CountryId ViewBag.Countries as SelectList Select Country new { id = countryDropdown }) @Html.DropDownListFor(model => model.StateId new SelectList(Enumerable.Empty () Value Text) Select State new { id = stateDropdown }) @Html.DropDownListFor(model => model.CityId new SelectList(Enumerable.Empty () Value Text) Select City new { id = cityDropdown })
