Is this a bug?
#1

I am using select2 version 4.0.13 I have tried version 4.1.0 too…
but the thing is it only select the first element by class and ignore the others im using this code to initialize select2

$(document).ready(function() {
	$(".mySelect").select2({
		placeholder : "Enter chart of account",
		allowClear: true
	});
});

Let me know if any one can help me…
