How to create accordion in JavaFX?

A title pane just a pane with a title. It holds one or more user interface elements like button, label, etc. you can expand and collapse it. An accordion is a container that contains one or more title pages, you can open only one title pane at a time.

You can create an Accordion in JavaFX by instantiating the javafx.scene.control.Accordion class. The getPanes() method returns the list which holds all the pane in the current accordion.

To add title panes to an accordion −

• Create a required number of title panes.

• Set contents to created panes.

• Retrieve ObservableList of the current accordion using the getPanes() method.

• Add all the created panes to the list using the addAll() method.

Example

import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Accordion;
import javafx.scene.control.RadioButton;
import javafx.scene.control.TitledPane;
import javafx.scene.control.ToggleGroup;
import javafx.scene.layout.VBox;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class AccordionExample extends Application {
   @Override
   public void start(Stage stage) {
      //Creating toggle buttons
      RadioButton button1 = new RadioButton("Apache Tika");
      RadioButton button2 = new RadioButton("JavaFX");
      RadioButton button3 = new RadioButton("Java ML");
      ToggleGroup group1 = new ToggleGroup();
      group1.getToggles().addAll(button1, button2, button3);
      //Adding the toggle button to the pane
      VBox box1 = new VBox(10);
      box1.setPadding(new Insets(10));
      box1.getChildren().addAll(button1, button2, button3);
      //Creating the TitlePane
      TitledPane pane1 = new TitledPane("Java Libraries", box1);
      pane1.setLayoutX(1);
      pane1.setLayoutY(1);
      //Creating toggle buttons
      RadioButton button4 = new RadioButton("HBase");
      RadioButton button5 = new RadioButton("MongoDB");
      RadioButton button6 = new RadioButton("Neo4j");
      ToggleGroup group2 = new ToggleGroup();
      group2.getToggles().addAll(button4, button5, button6);
      //Adding the toggle button to the pane
      VBox box = new VBox(10);
      box.setPadding(new Insets(10));
      box.getChildren().addAll(button4, button5, button6);
      //Creating the TitlePane
      TitledPane pane2 = new TitledPane("NoSQL Databases", box);
      pane2.setLayoutX(1);
      pane2.setLayoutY(1);
      //Creating a Accordion
      Accordion accor = new Accordion();
      accor.getPanes().add(pane1);
      accor.getPanes().add(pane2);
      VBox vbox = new VBox(accor);
      //Setting the stage
      Scene scene = new Scene(vbox, 595, 150, Color.BEIGE);
      stage.setTitle("Accordion Example");
      stage.setScene(scene);
      stage.show();
   }
   public static void main(String args[]){
