$('.my-select-box').fSelect();
$('#ClearSelect').click(function() {
$('#fselectMulti option:selected').removeAttr('selected');
$('.my-select-box').prev(".fs-dropdown").find(".fs-options .fs-option").each(function() {
$(this).removeClass('selected', false);
});
console.log($('#fselectMulti').val());
$('.fs-label').html('Select some options');
})
$('#CheckSelect').click(function(){
console.log($('#fselectMulti').val());
})
});
