Groups extension doesn’t allow to do that. But instead of using “groups” you can set onChange event handlers that will execute the necessary functionality:

[code]combo1.attachEvent(“onChange”,function(){
reloadCombo2();
reloadCombo3();
});
combo2.attachEvent(“onChange”,reloadCombo3);

function reloadCombo2(){
combo2.clearAll(true);
combo2.loadXML(url+"?parent1="+combo1.getActualValue());
}
function reloadCombo3(){
combo3.clearAll(true);
combo3.loadXML(url+"?parent1="+combo1.getActualValue()+"&parent2="+combo2.getActualValue());
}[/code]
