So I found that in JS this plugin adds an extra class to the body tag each time you click the hamburger so I removed that js code that which you can find in:
animated-fullscreen-menu/frontend/js/nav.js file.
Find and remove this string from js file -> ||jQuery(“body”).toggleClass(“afsmenu__lockscroll”)
Then just add this in your custom CSS:
#animatedfsmenu_css {
position: fixed!important;
}
And its done.
I came up with a trick. I installed a plugin called ‘Plugins Load Order’ and set ‘Ideal Interactive Map’ to load before any other plugin and it worked!!!
