title: Combo in dhtmlxGrid
body: <p>How can i set a combo in dhtmlxGrid?</p>
  
  <p>I did something like below, still when i dblclick on cell i am unable to see the combo.
  i have initialized a dhtmlxwindow and attached a 1c layout.
  Then attached a grid to cell a.</p>
  
  <pre><code>var dhxWindow = new dhtmlxWindow();
  var popupWin = dhxWindow.createWindow('winName', xPos, yPos, width, hieght);
  popupWin.setText(winTitle);
  popupWin.setModal(true);
  popupWin.denyPark();
  popupWin.denyResize();
  popupWin.show();
  popupWin.centerOnScreen();
  var layout = popupWin.attachLayout('1C');
  var mygrid = layout.cells('a').attachGrid();
  mygrid.loadXML('grid.jsp');
  
  And my jsp:
  
      &lt;%@page contentType="text/xml" pageEncoding="UTF-8"%&gt;
      &lt;rows&gt; 
      &lt;head&gt; 
           &lt;column width="50" type="ed" align="right" color="white" sort="str"&gt;Sales&lt;/column&gt;
      &lt;column width="80" type="co" align="left" sort="str"&gt;Shipping
          &lt;option value="1"&gt;1 Day&lt;/option&gt;
          &lt;option value="7"&gt;1 Week&lt;/option&gt; 
      &lt;/column&gt; 
      &lt;/head&gt; 
      &lt;row&gt; 
      &lt;cell&gt;&lt;/cell&gt;
      &lt;cell&gt;&lt;/cell&gt;
      &lt;/row&gt;
  &lt;/rows&gt;
  </code></pre>
