Hi, I've been looking a way to do that, i can manage it with igNumericEditor but not with igCombo.

$("#ddlMonedaMonto").igCombo({

dataSource: data,
 valueKey: "IdMoneda",
 textKey: "Nombre",
 selectedItems: [{ index: 0 }], //default moneda = USD
 keydown: function (evt, ui) {
 if (ui.key == 13) {
 $(document.activeElement).closest(".input-group").next().find("input").focus()
 }
 }
 });
