Here is an mcve version of the code you are following, to get you started :

import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class Test1 extends Application  {

    @Override
    public void start(Stage primaryStage) {
        try {
            StackPane page = (StackPane) FXMLLoader.load(this.getClass().getResource("test1.fxml"));
            Scene scene = new Scene(page);
            primaryStage.setScene(scene);
            primaryStage.show();
        }
        catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        launch(args);
    }
}

test1.fxml

and its controller:

import javafx.animation.TranslateTransition;
import javafx.fxml.FXML;
import javafx.scene.layout.VBox;
import javafx.util.Duration;

public class Test1Controller {

    @FXML private VBox statusContainer;

    private TranslateTransition showStatus;
    private TranslateTransition hideStatus;
    private boolean showsStatus = false;

    @FXML void initialize() {

        showStatus = new TranslateTransition(Duration.millis(250), statusContainer);
        showStatus.setByY(-100.0);
        showStatus.setOnFinished(event -> showsStatus = true);
        hideStatus = new TranslateTransition(Duration.millis(250), statusContainer);
        hideStatus.setByY(100.0);
        hideStatus.setOnFinished(event -> showsStatus = false);
    }

   public void toggleStatus() {
        if( showsStatus ) {
            showStatus.stop();
            hideStatus.play();
        }
        else {
            hideStatus.stop();
            showStatus.play();
        }
    }
}

Edit: you can add auto-hide of the sliding node to the controller:

public class Test1Controller {

    @FXML private VBox statusContainer;

    private TranslateTransition showStatus;
    private TranslateTransition hideStatus;
    private boolean showsStatus = false;
    private static final int AUTO_HIDE_DEALY = 5;

    @FXML void initialize() {

        showStatus = new TranslateTransition(Duration.millis(250), statusContainer);
        showStatus.setByY(-100.0);
        showStatus.setOnFinished(event -> {
            showsStatus = true;
            autoHide();
        });
        hideStatus = new TranslateTransition(Duration.millis(250), statusContainer);
        hideStatus.setByY(100.0);
        hideStatus.setOnFinished(event -> showsStatus = false);
    }

    public void toggleStatus() {
        if( showsStatus ) {
            hide();
        }
        else {
            show();
        }
    }

    private void show(){
        hideStatus.stop();
        showStatus.play();
    }

    private void hide(){
        showStatus.stop();
        hideStatus.play();
    }

    private void autoHide() {
        Duration duration = Duration.seconds(AUTO_HIDE_DEALY);
        PauseTransition transition = new PauseTransition(duration);
        transition.setOnFinished(evt ->{
            if( showsStatus ) {
                hide();
            }
        });
        transition.play();
    }
}
