How to implement multi select dropdown in the datatable editor

Question

I am trying to implement multi-select dropdown in the data table editor. But not able to figure out how to pass the options. I am using the select2 plugin. (https://editor.datatables.net/plug-ins/field-type/editor.select2)

Sample Code:

var opts = {
        "multiple": true,
        "placeholder": "Select Device Types"
    }

    var choice = [
    { label: "Oil", value: "Oil" },
    { label: "2",           value: "2" },
    { label: "3",           value: "3" },
    { label: "4",           value: "4" },
    { label: "5 (lowest)",  value: "5" }
    ]

var editor
function plot_table(){

    editor= new $.fn.dataTable.Editor( {

        data:[{'employee_name': "jijo"}],
        "table": "#emp_hierarchy_table",
        "fields": [{'name': 'employee_name', 'label': 'Emp Name', 'type':'select2','options': choice ,'opts':opts}]
    } );


    $('#emp_hierarchy_table').on( 'click', 'tbody td:not(:first-child)', function (e) {
        editor.inline( this );
    } );

    $('#emp_hierarchy_table').DataTable( {
        dom: "Bfrtip",
        data:[{'employee_name': "jijo"}],
        "ordering": false,
        columns: [{'data': 'employee_name', 'title': 'employee_name'}],
        buttons: [ { extend: "create", editor: editor }],
    } );

}

This is the output that I am getting. https://i.stack.imgur.com/T7GZQ.png
