<body onload=" WA_setSelectionsInChildList(rst_stati2_WAJA,MM_findObj('select'),MM_findObj('country'),0,0,false,': ');WA_setSelectionsInChildList(MM_findObj('country'), MM_findObj('state'),0,0,false,': ');WA_setSelectionsInChildList(MM_findObj('state') ,MM _findObj('city'),0,0,false,': ');WA_FilterAndPopulateSubList(rst_stati2_WAJA,MM_findObj('select'),MM_findObj('country'),0,0,false,': ');WA_FilterAndPopulateSubList(rst_regioni_WAJA,MM_findObj('country'),MM_findObj('state'),0,0,false,': ');WA_FilterAndPopulateSubList(rst_provincie_WAJA,MM_findObj('state'),MM_findObj('city'),0,0,false,': ')">
my select are
1) select (populate country)
2) country (populate state)
