Hi,

we use Odoo 14 and I would like to show a button in our website after certain scroll position. This basic JS code below calculates vertical scroll and when it reaches half of the window height, it adds active class to the button. So, it shows the button. When I run this code in an simple HTML project, it works but same code doesn't work in Odoo. Is there any idea that how can I do that?

window.addEventListener("scroll", (event) => {        
	​var scroll = this.scrollY;        
	​if (scroll >= window.innerHeight / 2 ) {
	​	​document.getElementById("IdButton").classList.add("active");
	​} ​else {
	​	​document.getElementById("IdButton").classList.remove("active");
	​}      
});
