select2("open"); is not working
You can use two case:
Case 1: Not run before select2 because you run before select2, it changes on HTML. Therefore you call function not run. You use code below:
$(".js-example-events").on("click", function () {
$("#s1").select2();
$("#s1").select2("open");
$(this).select2();
$(this).select2("open");
});
Case 2: Keep your code you need call event to code below:
$(".js-example-events").select2();
$("span[class='select2-selection select2-selection--
single']").on("click",
function () {
$("#s1").select2("open");
$(this).select2("open");
});
