Freeze the Background when Floating Group is up

Can somebody help me with this. When I open Floating group, I should not be able to scroll the background. I have also made the floating group Fixed height but it doesn’t work.

To turn off scrolling when FG is visible, you can do the following:

  1. Add an ID to the page, for example: “myPage”
  2. Add a “Run Javascript” step to the action that is responsible for showing FG with the following JS code inside it:
savedScrollY = window.scrollY; 
let x = document.getElementById("myPage"); 
x.style.position = "fixed"; 
x.style.top = -savedScrollY+"px";

This will disable scrolling on the page.

  1. Add a “Run Javascript” step to the action that is responsible for hiding FG with the following JS code inside it:
let x = document.getElementById("myPage"); 
x.style.position = "absolute"; 
x.style.top = "";

resetscroll();

This will enable scrolling on the page again.

Wow! It really worked… Thanks @marpas
