I'm not sure I fully understand your idea. If you want to have VerticalScrollBar for your RadMenuItem
, you should put it inside the header. RadMenuItem's
header is of type object so you can put whatever you need.
If you want to have scrollbar for the submenu items (for example if you have a lot of items and you want to scroll through all of them), you can check this article
for more information how to achieve it.
Hopefully this helps.
All the best,
