I couldn’t able to inspect the scroll in the browser as from where it is reflecting and you can see the scrollbar as well in the application.is there any way implementing scrollbars out of the box in the mendix.
The easiest way to implement scroll bars in Mendix is by implementing them in your page layout. On a layout you can add a scroll container. (for more information on Layouts: https://docs.mendix.com/refguide/layout/)
If that is not what you want, you can achieve a scroll container by implementing CSS styling on page elements.
