Hi, There is any way to change the size of a PopupMenu. Actually i’m using menu = system.gui.createPopupMenu to generate a Popup, the problem is that the Popup is to small (it doesn’t have à scrollbar). I need to show more the 50 items. Have you any idea how put un scrollbar or change the size of a popup? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/7/e/7e61a45e53d723f1cfd7c2fe7ec532d1dc16fc2f.png) I’m using Vision 8.1. Thanks ---

You can reach into advanced Swing coding and create your own popup menu - I’d suggest using [`JidePopupMenu`](http://www.jidesoft.com/javadoc/com/jidesoft/swing/JidePopupMenu.html) as your base class, because it has some builtin niceties, such as scrolling if your menu items won’t fit on the screen. There’s probably some examples floating around this forum to get you started on the custom menu aspect. ---

Hi PGriffith, I have tried to use the object but I do not have the necessary Java skills to do it. Can you guide me to some website or give me an idea to get started? How can I implement your suggestion in Ignition. I would really appreciate your help. Thanks a lot ---

Low level Jython tutorials are few and far between.

Hi PGriffith: It has been some time since the last time. In fact, I have had to attack other points of the application in which I am working. Now I have a little more time and I have taken up the problem of this topic. However, I am still stuck, here is what I have done: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/1/a1b2442c749b1acd44279e6607bad78fec857d17.png) Here is the result: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/3/839cb6f876e4c1a40fab0c64669e2f3231c53e39.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/6/3/6305024e101febfda1c0ec9e6ddd6e166e449887.png) The scrollbar still does not appear. If I not wrong, the JpopupMenu have acces of all attributs of Jcomponent, so the scrollable attribute. So, I don’t understand why it doesn’t appear. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/5/c5a723a4611f8e4344618f4a165c081e450f9270.png) Could you tell me where is the problem?

JPopupMenus don’t automatically scroll, and you’re making a `JyPopupMenu` anyways. You _must_ use `JidePopupMenu` as your base class if you want the automatic scrolling behavior. The code to add new items should be basically the same. ---

It’s not my component, but yes, it’s supposed to do what you want: ```auto public class JidePopupMenu extends JPopupMenu implements Scrollable This component extends JPopupMenu and adds a method to display the menu inside the screen even if the mouse pointer is near the edge of the screen. It also puts the menu items into a scroll pane. When there are too many menu items that can't fit into one screen, the scroll pane will scroll up and down so that you can still get to all menu items. ``` I don’t know why it’s not doing what it’s supposed to. ---

JYPopupMenu as the base class shows a scroll bar. I wouldn’t recommend running this out of the script console, though that’s where I wrote it: ```auto from javax.swing import JMenuItem from de.javasoft.widgets import JYPopupMenu from functools import partial menu = JYPopupMenu() def saySomething(event, message): system.gui.messageBox(message, "Event") messages = [str(i) for i in range(1, 100)] for message in messages: handler = partial(saySomething, message=message) item = JMenuItem("Say %s" % message, actionPerformed=handler) menu.add(item) menu.show(None, 1280, 800) ``` ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/7/b/7b73ee8a90d100b169c578db1fdfef970ce16f7e.png) ---

This is great and works as expected, thanks! Can this script be adapted to maintain the nested list functionality of system.gui.createPopupMenu? It gets hung up when passing the submenu names and functions. ---

Instead of creating `JMenuItems`, create your own `JMenu`s (sibling import to `JMenuItem`) and add your nested menus to them. Constructing that automatically I’ll leave as an exercise for the reader. We could probably change `system.gui.createPopupMenu` to use this different base class automatically, but it won’t happen anytime soon, so you’re probably still better off using a workaround. ---
