title: How can I populate select boxes with multiple values?
body: <p>I'm setting up a jqGrid which needs to visualize multiple values in one cell. The input comes from a form where the user can select multiple choices. I am able to display the select box, but not populate it. I have tried to insert an array in the JSON object, but to no success.</p>
  
  <p>This is the model:</p>
  
  <pre><code>index:'ship', editoptions:{multiple:true, value:{1:”FedEx”,2:”InTime”,3:”TNT”,4:”ARAMEX”}}
  </code></pre>
  
  <p>And here are some variations of the data I've tried populating with:</p>
  
  <pre><code>ship:{[1],[4]}
  ship:[[1],[4]]
  ship:{value:{1,4}}
  </code></pre>
  
  <p>...and lots of other variations.</p>
  
  <p>I've also searched the jqGrid forum, but didn't find a solution. How can I fix this problem?</p>
