JavaScript File Code

function bindDropDown(apiUrl, dropDownId) {
        $.ajax({
            type: "GET",
            url: apiUrl,
            dataType: "json",
            success: function (result) {
                var recordsDocument = jQuery.parseJSON(result);

                //Assgin records value into drop down
                $.each(recordsDocument, function (text, data) {
                    if (data == 0) {
                        $("#" + dropDownId + "").append("<option value=" + data.Value + " selected='selected'>" + data.Text + "</option>");
                    } else {
                        $("#" + dropDownId + "").append("<option value=" + data.Value + ">" + data.Text + "</option>");
                    }
                });
            }
        });

ApiUrl page Code

public string GetDropDownListDocument()
    {
        try
        {
            List<SelectListItem> recordsDocument = new List<SelectListItem>();

                recordsDocument =
                    _docStyleRepository.GetAll()
                                       .OrderBy(c => c.DocDescription)
                                       .AsEnumerable()
                                       .Select(k => new SelectListItem
                                       {
                                           Text = k.DocDescription,
                                           Value = k.Id.ToString(CultureInfo.InvariantCulture)
                                       }).ToList();
            //Created the empty item list
            var emptyItem = new SelectListItem { Selected = true, Value = "0", Text = "---Select---" };

            //Added the empty item at the top of the list
            recordsDocument.Insert(Utilities.ZERO, emptyItem);

            return JsonConvert.SerializeObject(recordsDocument); //Return result
        }
        catch (Exception exception)
        {
            return null;
        }
    }
