How to make a form with JSF with a field that can have as many values as needed?

Considering the following entity class:

import java.io.Serializable;
import java.util.List;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.SequenceGenerator;



@Entity
@SequenceGenerator(name = "cliente_sequencia", sequenceName = "cliente_sequencia",
        allocationSize = 1, initialValue = 1)
public class Cliente implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "cliente_sequencia")
    private int id;
    private String cpf;  
    private String nome;
    private String email;  
    private List<String> telefones;   

    public Cliente(){
    }

    public Cliente(String cpf, String nome, String email, List<String> telefones) {
        this.cpf = cpf;
        this.nome = nome;
        this.email = email;
        this.telefones = telefones;
    }

    public int getId() {
        return id;
    }


    public String getCpf() {
        return cpf;
    }

    public void setCpf(String cpf) {
        this.cpf = cpf;
    }

    public String getNome() {
        return nome;
    }

    public void setNome(String nome) {
        this.nome = nome;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public List<String> getTelefones() {
        return telefones;
    }

    public void setTelefones(List<String> telefones) {
        this.telefones = telefones;
    }
    public void addTelefone(String telefone) {
        telefones.add(telefone);
    }
    public void removeTelefone(String telefone) {
        telefones.add(telefone);
    }

    @Override
    public String toString() {
        return "Cliente{" + "id=" + id + ", cpf=" + cpf + ", nome=" + nome + ", email=" + email + ", telefones=" + telefones + '}';
    }

}  

Having this driver:

@Named
@RequestScoped
public class Controlador2 implements Serializable{

    private Cliente cliente =  new Cliente(); 
    @EJB
    private ClienteDAO servico = new ClienteDAO();

    private List<Cliente> todos = new ArrayList<>();

    public String redirecionar(){

        return "index.xhtml";
    }
    public String salvar(){
        servico.salvar(cliente);
        todos = servico.todos();
        return "listaTodos.xhtml";
    }

    public Cliente getCliente() {
        return cliente;
    }

    public void setCliente(Cliente cliente) {
        this.cliente = cliente;
    }

    public List<Cliente> todos() {
        return servico.todos();
    }

    public void setTodos(List<Cliente> todos) {
        this.todos = todos;
    }


}

How could I create a form with jsf that had a field where I could insert a list of phones? I've never done anything like that !!
