Have you looked into ControlsFx Popover control.

import org.controlsfx.control.PopOver;
import org.controlsfx.control.PopOver.ArrowLocation;

private PopOver item;

final Scene scene = addItemButton.getScene();

final Point2D windowCoord = new Point2D(scene.getWindow()
        .getX(), scene.getWindow().getY());

final Point2D sceneCoord = new Point2D(scene.getX(), scene.
                getY());

final Point2D nodeCoord = addItemButton.localToScene(0.0,
                        0.0);
final double clickX = Math.round(windowCoord.getX()
    + sceneCoord.getY() + nodeCoord.getX());

final double clickY = Math.round(windowCoord.getY()
        + sceneCoord.getY() + nodeCoord.getY());
item.setContentNode(addItemScreen);
item.setArrowLocation(ArrowLocation.BOTTOM_LEFT);
item.setCornerRadius(4);                            
item.setDetachedTitle("Add New Item");
item.show(addItemButton.getParent(), clickX, clickY);

This is only an example but a PopOver sounds like it could accomplish what you want. Check out the documentation for more info.

Important note: ControlsFX will only work on JavaFX 8.0 b118 or later.

You can either create a new Stage  add your controls into it or if you require the POPUP as Dialog box  then you may consider using DialogsFX or ControlsFX Requires JavaFX8   For creating a new Stage  you can use the following snippet   Override public void start final Stage primaryStage        Button btn   new Button        btn setText  Open Dialog        btn setOnAction          new EventHandler lt ActionEvent gt                   Override             public void handle ActionEvent event                    final Stage dialog   new Stage                    dialog initModality Modality APPLICATION MODAL                   dialog initOwner primaryStage                   VBox dialogVbox   new VBox 20                   dialogVbox getChildren   add new Text  This is a Dialog                     Scene dialogScene   new Scene dialogVbox  300  200                   dialog setScene dialogScene                   dialog show                                       If you don t want it to be modal  block other windows   use    dialog initModality Modality NONE

The Popup class might be better than the Stage class  depending on what you want   Stage is either modal  you can t click on anything else in your app  or it vanishes if you click elsewhere in your app  because it s a separate window    Popup stays on top but is not modal   See this Popup Window example
