title: JQuery change selected value after clone dropdown
body: <p>I have this dropdown. I need clone for my other dropdown lists:</p>
  
  <pre><code>&lt;select name="general"&gt;
  &lt;option value="0" style="font-size:11px"&gt;Nothing&lt;/option&gt;
  &lt;option class="dropdown_root" value="1"&gt;Admin&lt;/option&gt;
  &lt;option class="dropdown_root_first_lvl" value="2"&gt;General&lt;/option&gt;
  &lt;option class="dropdown_root_next_lvl" value="3"&gt;Group&lt;/option&gt;
  &lt;option class="dropdown_root_next_lvl" value="4"&gt;Sales&lt;/option&gt;
  &lt;/select&gt;
  
  &lt;select name="group"&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>My problem is I want to clone the same content but I want the value selected from the list "group" is "Group" ... whose value is 3</p>
  
  <p>I tried this:</p>
  
  <pre><code>var new_dd = $('select[name="general"] option').clone();
  new_dd.val('3').attr('selected','selected').appendTo('select[name="group"]');
  </code></pre>
  
  <p>but I find this:</p>
  
  <pre><code>&lt;select name="group"&gt;
  &lt;option value="3" style="font-size:11px" selected="selected"&gt;Nothing&lt;/option&gt;
  &lt;option class="dropdown_root" value="3" selected="selected"&gt;Admin&lt;/option&gt;
  &lt;option class="dropdown_root_first_lvl" value="3" selected="selected"&gt;General&lt;/option&gt;
  &lt;option class="dropdown_root_next_lvl" value="3" selected="selected"&gt;Group&lt;/option&gt;
  &lt;option class="dropdown_root_next_lvl" value="3" selected="selected"&gt;Sales&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>I want to see is:</p>
  
  <pre><code>&lt;select name="group"&gt;
  &lt;option value="0" style="font-size:11px"&gt;Nothing&lt;/option&gt;
  &lt;option class="dropdown_root" value="1"&gt;Admin&lt;/option&gt;
  &lt;option class="dropdown_root_first_lvl" value="2"&gt;General&lt;/option&gt;
  &lt;option class="dropdown_root_next_lvl" value="3" selected="selected"&gt;Group&lt;/option&gt;
  &lt;option class="dropdown_root_next_lvl" value="4"&gt;Sales&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>How could obtain this?</p>
