AutoSuggestBehaviour in ADF

1.Create a text Box
2.Inside the text box drag and drop a autoSuggestBehaviour component
3.In the SuggestedItems create a managed bean for countrySuggester.getCountries
4.Now your Jsf will look like this,
<af:inputText label="Country" value="#{item.country}"
                                        columns="20" id="it5">
                <af:autoSuggestBehavior suggestedItems="#{countrySuggester.getCountries}"/>
        </af:inputText>

5.In the countrySuggester class make it as this,

import java.util.ArrayList;
import java.util.List;

import javax.faces.model.SelectItem;

public class CountrySuggester {

  private List<SelectItem> countries = new ArrayList<SelectItem>();

  public CountrySuggester() {
    super();
    countries.add(new SelectItem("Belgium"));
    countries.add(new SelectItem("Hungary"));
    countries.add(new SelectItem("Bulgaria"));
    countries.add(new SelectItem("India"));
    countries.add(new SelectItem("Indonesia"));
    countries.add(new SelectItem("United Kingdom"));
    countries.add(new SelectItem("United States of America"));
    countries.add(new SelectItem("Netherlands"));
    countries.add(new SelectItem("Nepal"));
    countries.add(new SelectItem("Namibia"));

  }
 
  public List<SelectItem> getCountries(String country) {
    List<SelectItem> items = new ArrayList<SelectItem>();
    for(SelectItem item:countries){
      if (item.getLabel().startsWith(country)) {
        items.add(item);
      }
    }
    return items;
  }
}
