Description
A form select element like:
<select id="breakfast"><option>included</option><option>excluded</option></select>
will not have it's selectedIndex cloned if it is set on the fly. For instance if the user selects a specific template which will set some values in the form (including the above select to excluded). The cloned element will have a selectedIndex of 0 instead of 1.
element = $('#' + part + ' input[type!="hidden"], #' + part + ' select, #' + part + '[type="checkbox"]');
element.each(function(i, e) {
c = $(e).clone();
$(e).attr({name: 'showforhidden', disabled: true}).after(c.attr('disabled', false).hide());
});
The idea of this piece of jQuery is to append the original (now hidden) element after the new visible but disabled element.

I think that is to be expected. The .selectedIndex is a property of the dynamic DOM element's state and not an attribute in the tag's markup. According to the W3C, the DOM cloneNode() only copies attributes:
http://www.w3.org/TR/DOM-Level-2-Core/core.html
Browsers aren't consistent, however; if you cloned an input[type=text] it uses the current value property that reflects input the user typed. And I know we've tried to play heroics with check boxes on this.

My inclination is to close this wontfix because it's not worth the extra code for the few times people need it.

agreed. Users can reselect if necessary.

Although reselecting is not possible since the new element will replace the current and be disabled, while the other is hidden. This ensures a 'template-like' form, in which the user will see some values set but cannot change them. The hidden elements are required to send over required data.
I agree that the most simple fix is to manually carry over the selectedIndex as I have done now. Thanks for the responses!
