            <f:selectItems value="#{search.departments}" />  

        </p:selectOneMenu>

public class SearchBean implements Serializable {

private Map<String, Map<String, String>> courseData = new HashMap<String, Map<String, String>>();

private Map<String, String> departments = new HashMap<String, String>();
private String selectedDepartment;


    departments.put("department1",
            "department1");
    departments.put("department2",

with LinkedHashMap it is ordered not sorted i.e you get it in order which you put the items, but if you use TreeMap then it is sorteted alphabetically

It's not sorted because HashMap doesn't have a predictable iteration order. Try LinkedHashMap instead.
