You can add item in between based on item index. If you add new item without item index, item will be added as last item in list.

The following example demonstrate how to add item in between in DropDownList.

var sportsData = [
    { Id: 'game1', Game: 'Badminton' },
    { Id: 'game2', Game: 'Football' },
    { Id: 'game3', Game: 'Tennis' }
//initiate the DropDownList
var dropDownListObject = new ej.dropdowns.DropDownList({
    // bind the sports Data to datasource property
    dataSource: sportsData,
    // maps the appropriate column to fields property
    fields: { text: 'Game', value: 'Id' },
    //set the placeholder to DropDownList input
    placeholder: "Select a game"
//render the component
// add item at first
document.getElementById('first').onclick = () => {
    dropDownListObject.addItem({ Id: 'game0', Game: 'Hockey' }, 0);
// add item in between
document.getElementById('between').onclick = () => {
    dropDownListObject.addItem({ Id: 'game4', Game: 'Golf' }, 2);
// add item at last
document.getElementById('last').onclick = () => {
    dropDownListObject.addItem({ Id: 'game5', Game: 'Cricket' });
