[Solved] ContextMenu opens and immediately closes after scroll

[Sean]

Hi, 

We’re experiencing an issue with Kendo ContextMenu when using Kendo UI for jQuery 2025.4.1217 with jQuery 3.7.1.

Our application uses a common UI pattern: a Kendo Grid with a button in each row that opens a ContextMenu.

On narrower screens (approximately < 1850px width), an intermittent issue occurs when users scroll down to the bottom of the grid. For rows near the bottom of the page, clicking the button causes the ContextMenu to open and immediately close. When this happens, the page also performs a brief scroll up and down. Refreshing the page or navigating away and back typically resolves the issue.

This behavior is intermittent. Often the page loads and the ContextMenus function correctly, even on narrower screens.

We are also running older versions of Kendo UI (2024 and 2021) and do not see this behavior in those environments.

I've been able to recreate this in the dojo here: https://dojo.telerik.com/sTKnXHRp

Steps to reproduce

Please note that the issue may require multiple attempts to appear:

1. Open the Dojo link above.
2. Open your browser’s developer tools and set the responsive screen width to less than 1850px (height does not seem to matter).
3. Scroll to the bottom of the page.
4. Immediately click one of the lower buttons that opens a ContextMenu.
5. If the page enters the “broken” state, the ContextMenu will open and immediately close.

I have a screen recording of this occurring in the Dojo, but the file upload does not support MP4 files.

We’ve tried various ContextMenu configuration options related to positioning, collision handling, and alignment, but none have resolved the issue.

Any guidance or insight would be greatly appreciated

Thanks,

Sean
