how to make body not scroll through menu bar

Question

I want when touching the menu, the body to be non scrollable. I can scroll the body when scrolling on main content but i dont want to scroll the body when touching the mobile menu. How can I do that?

Answer 1

Basically the menu “onOpen” even should trigger a change in the body's style to overflow: hidden; and menu “onClose” event should trigger a change in body's style to overflow: auto;

Without further details on your case, it's hard to elaborate.
