I Want To Use Multiple Select2 Onchange Function In A Dynamic Way

I want to put select2 function in my code but don't know where to put that .select2() function i have this .append($()) my mode

Solution 1:

Insert CSS & JS file in your page then after JS file insert this code in your page.

<scripttype="text/javascript">
    $(document).ready(function() {
        $('#neww').select2();
    });
</script>

To update options, see below code.

var option = newOption("text", "id");
$("#neww").append(option);
$("#neww").trigger("change");
