I have the following HTML:
Updated fiddle.
I suggest to use a container then append the element you want to it, check the example below.
Hope this helps.
$(function() {
var cond1 = $('#condition_value_1');
var cloned_cond1 = cond1.clone();
var cond1_select = '';
$('#showme').click(function() {
$("#my-container").html(cond1_select);
$("#condition_value_1").select2({placeholder: 'Select choice',width:'100%'});
});
$('#clickme').click(function() {
if ($('#condition_value_1').hasClass('select2-hidden-accessible')) {
$("#condition_value_1").select2('destroy');
}
$("#my-container").html(cloned_cond1);
$("#condition_value_1").show();
});
});
