Here is my source code :

List localOptions = new ArrayList();
Select localSelect = new Select("local.numLocal","Lieu de travail");

List<Local> listCollege = new LocalDAO().findByCommuneAndType(communeSelect.getValue(),"Collège");
List<Local> listSSD = new LocalDAO().findByCommuneAndType(communeSelect.getValue(),"SSD");
List<Local> listPMI = new LocalDAO().findByCommuneAndType(communeSelect.getValue(),"PMI");
List<Local> listCDDS = new LocalDAO().findByCommuneAndType(communeSelect.getValue(),"CDDS");
List<Local> listCGVO = new LocalDAO().findByCommuneAndType(communeSelect.getValue(),"CGVO");

if (!listCollege.isEmpty()) {
OptionGroup college = new OptionGroup("Collège");
for (Iterator iter = listCollege.iterator(); iter.hasNext()

{ Local element = (Local) iter.next(); college.add(new Option(element.getNumLocal(),element.getLibLocal())); }

localOptions.add(college);
}

if (!listSSD.isEmpty()) {
OptionGroup ssd = new OptionGroup("SSD");
for (Iterator iter = listSSD.iterator(); iter.hasNext()

{ Local element = (Local) iter.next(); ssd.add(new Option(element.getNumLocal(),element.getLibLocal())); }

localOptions.add(ssd);
}

if (!listPMI.isEmpty()) {
OptionGroup pmi = new OptionGroup("PMI");
for (Iterator iter = listPMI.iterator(); iter.hasNext()

{ Local element = (Local) iter.next(); pmi.add(new Option(element.getNumLocal(),element.getLibLocal())); }

localOptions.add(pmi);
}

if (!listCDDS.isEmpty()) {
OptionGroup cdds = new OptionGroup("CDDS");
for (Iterator iter = listCDDS.iterator(); iter.hasNext()

{ Local element = (Local) iter.next(); cdds.add(new Option(element.getNumLocal(),element.getLibLocal())); }

localOptions.add(cdds);
}

if (!listCGVO.isEmpty()) {
OptionGroup cgvo = new OptionGroup("CGVO");
for (Iterator iter = listCGVO.iterator(); iter.hasNext()

{ Local element = (Local) iter.next(); cgvo.add(new Option(element.getNumLocal(),element.getLibLocal())); }

localOptions.add(cgvo);
}
localSelect.setOptionList(localOptions);
localSelect.setRequired(true);
