Any chance you could give me an example of how to add a method to the combobox?  I've tried something similar to your example with the DataSource, but it's telling me that Combo doesn't have an extend method.

Neither of these work:

$.ui.igCombo.extend

$.ig.Combo.extend

Hi Josh,

I wrote for you a sample which extends igCombo, adds custom border and ability to set datasource from string with coma separators.

<script type="text/javascript">
 $.widget('ui.igMyCombo', $.ui.igCombo, {
  options: {
   myBorder: null,
   myStringData: null
  },
  _create: function () {
   $.ui.igCombo.prototype._create.apply(this);
   var border = this.options.myBorder, data = this.options.myStringData;
   if (border) {
    this.mainElem.css('border', border);
   }
   if (data) {
    this.options.dataSource = data.split(',');
    this.dataBind();
   }
  }
 });
 //
 // example to use
 $(function () {
  $('#combo1').igMyCombo({
   mode: 'dropdown',
   myBorder: '1px solid red',
   myStringData: 'one,two,three,four'
  });
 });
</script>
<span id="combo1"></span>
