Dropdown to display one field and update another

nicontrols

I have a dropdown that is populated depending on a part number:

            editor.dependent( 'salstkmaster.partnum', function ( val, data, callback ) {
                 
                $.ajax( {
                    url: 'datatables.php',
                    data: { action: "supplier", value: val },
                    type: 'POST',
                    dataType: 'json',
                    success: function ( json ) {
                        callback( json );
                    }
                });
            });

This uses the salstkitem.supplier field, and lets imagine it produces the following:

<option value="1">A</option>
<option value="2">B</option>
<option value="3">C</option>

How can I get this field to update the enqitem.itemid field? Rather than salstkitem.supplier?

I have tried adding the following to my DataTable:

{ data: "salstkitem.supplier", editField: "enqitem.itemid" }

But this stops the dropdown from working. Any ideas?
If more information is required I can provide it, I just tried to cut stuff out for brevity.

What fields the callback on the dependent() method perform depends entirely on the JSON that you are sending back. e.g. to change the options in enqitem.itemid you would use a JSON structure such as:

{
  "options": {
    "enqitem.itemid": {
       // ... options
     }
  }
}
