I am passing elements from one section to another, the big problem I have, is that when cloning it does not save the option selected, simple example to understand me:

<div id="content">
  <div class="copy">
    <select>
      <option value="volvo">Volvo</option>
      <option value="saab">Saab</option>
      <option value="mercedes">Mercedes</option>
      <option value="audi">Audi</option>
    </select>
  </div>
</div>
<button type="button" id="clone">Clonar</button>
<div id="container">

</div>



 $('#clone').on('click', function() {
     $('#content .copy').clone().appendTo('#container')
 }

It clones it perfectly, but still does not keep the information that was selected. Someone knows what is going on or what other method they recommend me to use.

jQuery has a limitation on the clone function. The relevant part translated:

Note: For performance reasons, the dynamic state of certain form elements (eg: data entered by the user in textarea and selections made in select ) is not copied to the cloned elements. [...]

But you can return to assign the value to the new element after it has been added to the page:

$('#clone').on('click', function() {
  var original = $('#content .copy');
  var valor = original.find('select').val();
  var clon = original.clone().appendTo('#container');
  clon.find('select').val(valor);
});
