Dropdown field binding issue

[avair]

Below is the javascript function which i am using to bind values to the dropdown using ddlCou.innerText = option.text; only the last option is getting displayed as a label but i need to have a dropdown functionality with select at first and remaining all values which are in result[i]

function loadCountriesDropDown() {
        var ddlCou = document.getElementById('ddlCountriesId');
        var countyStates = [];
        for (var i = 0; i < data.List.length; i++) {
            countyStates.push(data.List[i].Name);
        }
        var result = countyStates.map(function (obj) { return obj.Name; });
        result = result.filter(function (v, i) { return result.indexOf(v) == i; });
        for (var i = 0; i < result.length; i++) {
            var option = document.createElement("option");
            option.text = result[i];
            ddlCou.innerText = option.text;
        }
}

<ext:ComponentColumn runat="server">
  <Items>
    <ext:DropDownField runat="server" ID="ddlCountriesId" ClientIDMode="Static"></ext:DropDownField>
  </Items>
</ext:ComponentColumn>

Hello, @avair!

The DropDownField component is meant to display a complex component as the dropdown box, so it doesn't really handle multiple data, the underlying component "picker" does. Take a look at its overview example: Form > Dropdown Field > Overview

Perhaps what you need is a read-only combo box? Or a searchable combo box which requires a valid selection from the list of accepted entries? Take a look at this example: Form > Combo Box > Ajax Linked Combos for it has both examples mentioned, respectively.

Hope this helps!
