The option
element maintains its current selectedness with the selected
javascript property (not to be confused with the selected
attribute, which corresponds to default selectedness).
Since jQuery’s clone
doesn’t clone the current selectedness (http://bugs.jquery.com/ticket/1294) , you’ll have to do it manually:
$('#form-to-submit').html($(fieldsetName).clone());
$('#form-to-submit select').val($('.fieldsetwrapper select').val());
