Updated editable-select.pack.js

I am trying to create an editable first item within my select list but the script listed below is throwing a 404. Is there an updated src i should be using?

<script type="text/javascript" src="jquery.editable-select.pack.js"></script>

Below is the code for my SelectList:

<td>@Html.DropDownListFor(m => m.test.model, new SelectList(new[] { "", "FCU", "Bellows" }), new { @id = "models"})</td>

This is the method for changing the edit:

$(function () {
    $('#models').editableSelect({
        bg_iframe: true,
        onSelect: function (list_item) {
            $('#results').html('List item text: ' + list_item.text() + '<br/> \
Input value: ' + this.text.val());
        }
    });
    var select = $('.editable-select:first');
    var instances = select.editableSelectInstances();
    if (instances != null
        && instances != undefined
        && instances.length > 0) instances[0].addOption("Item 1");
});

I was unaware I was asking for the jquery-editable-select CDN.

<script src="https://cdn.jsdelivr.net/npm/jquery-editable-select@2.2.5/dist/jquery-editable-select.min.js"></script>

Found it here:
