Layout customization of Joptionpane

Question

I have the following structure of my Joptionpane, with horizontal typing fields:

How to vertical the input fields?

Here below is the class code:

import javax.swing.*; 

public class JOptionPaneMultiInput {
   public static void main(String[] args) {
      JTextField fieldNome = new JTextField(5);
      JTextField fieldTelefone = new JTextField(5);
      JTextField fieldEmail = new JTextField(5);
      JPanel myPanel = new JPanel();
      myPanel.add(new JLabel("Digite Nome:"));
      myPanel.add(fieldNome);
      myPanel.add(Box.createHorizontalStrut(15)); // a spacer
      myPanel.add(new JLabel("Digite Telefone:"));
      myPanel.add(fieldTelefone);
      myPanel.add(Box.createHorizontalStrut(15)); // a spacer
      myPanel.add(new JLabel("Digite Email:"));
      myPanel.add(fieldEmail);

      int result = JOptionPane.showConfirmDialog(null, myPanel, 
               "Entrada de valores", JOptionPane.OK_CANCEL_OPTION);
      if (result == JOptionPane.OK_OPTION) {
         System.out.println("Nome value: " + fieldNome.getText());
         System.out.println("Telefone value: " + fieldTelefone.getText());
         System.out.println("Email value: " + fieldEmail.getText());
      }

   }
}

Answer 1

With the help of @Wakim with the use of Gridlayout I managed, as a result in the figure below:

Code added below, resulting in the fields in the vertical position:

 GridLayout experimentLayout = new GridLayout(0,1);
 myPanel.setLayout(experimentLayout);
