title: Using jqGrid, Is there anyway to have dynamic dropdown in the edit record popup?
body: <p>I have a record that has three fields and they are all dropdowns.  It all works fine if they are independent records but i would like it where if you change the first dropdown, then the list of items in the second dropdown changes?  Is this possible in jqgrid.</p>
  
  <p>Simplified version of my code looks like this now:</p>
  
  <pre><code>jQuery("#marketDataGrid").jqGrid({
      mtype: "POST",
      url: "/Application/MarketData/" + id,
      datatype: "json",
      colNames: ["", "Id","Source", "API"],
      colModel: [
          { name: "ApplicationId", index: "ApplicationId", hidden: true, width: 0, editable: true, editoptions: { readonly: true} },
          { name: "Id", index: "Id", hidden: false, width: 30, editable: false, editoptions: { readonly: true} },
          { name: "MarketDataSource", index: "MarketDataSource", editoptions: { dataUrl: "/MarketDataSource/GetSelectDataRequired" }, editrules: { required: true }, editable: true, edittype: "select", width: 155, stype: 'select', searchoptions: { sopt: ['eq', 'ne'], dataUrl: "/MarketDataSource/GetSelectData"} },
          { name: "API", index: "API", editoptions: { dataUrl: "/API/GetSelectDataRequired" }, editrules: { required: true }, editable: true, edittype: "select", width: 155, stype: 'select', searchoptions: { sopt: ['eq', 'ne'], dataUrl: "/API/GetSelectData"} }
  
      ],
  </code></pre>
