title: Add multiple input elements in a custom edit type field
body: <p>Is there a way to create a custom field that has multiple input elements?  I'm consulting the <a href="http://www.trirand.com/jqgridwiki/doku.php?id=wiki:common_rules&amp;s[]=custom" rel="noreferrer">documentation</a> and creating a single input element is pretty straight forward, but I'm not exactly sure how you'd add more than one.</p>
  
  <p>Has anyone crossed this bridge before?  If so, how did you do it?</p>
  
  <p>Here's some sample code:</p>
  
  <pre><code>...
  {name: 'Dimensions', index: 'Dimensions', hidden: true, editable: true, 
  edittype: 'custom', editoptions: {custom_element: dimensionsElement, 
  custom_value: dimensionsValue}, editrules: {edithidden: true}},
  ...
  
  
  function dimensionsElement(value, options) {
      var el = document.createElement("input");
      el.type = "text";
      el.value = value;
      return el;
  }
  
  function dimensionsValue(elem) {
      return $(elem).val();
  }
  </code></pre>
