Please enhancing <q-menu> component

[wenbinwumei]

Hi, I suggest enhancing some features of. I need an effect similar to the Windows right-click menu, such as scrolling to expand subsets and scrolling to close subsets. I tried to implement it, but there was a conflict between scrolling out the parent and scrolling in the child. I don't know how to implement it. If the component itself can support it, that would be great
