Scrolling div/section with indicators

I want to create a vertical scrolling div with an active indicators. However I'm having trouble with it event firing on the div targeted. I set it to window.addEventListener it works fine at full height of the window but if I set it to div.addEventListener it's not firing inside of the element at all. I'm Hoping someone has some pointer for this. Here's what I got so far.
section.scroller {
max-width: 900px;
margin: auto;
background: antiquewhite;
scroll-behavior: smooth;
position: relative;
width: 100%;
height: 100%;
overflow-y: scroll;
overflow-x: hidden;

// padding: 0 17px;
box-sizing: content-box;
}
.sec {
min-height: 100vh;
// width: 100vw;
display: flex;
align-items: center;
justify-content: center;
scroll-behavior: smooth;
// width: 100%;
&:nth-child(odd) {

jQuery - Toggle menu without using stopImmediatePropagation();

Currently the snippet only allows toggling of each menu when I un-comment the e.stopImmediatePropagation();.
The problem is I cannot use e.stopImmediatePropagation(); because I have to use an animation on the .button that would be killed by the stop.
How do I change the code to be able to toggle the menu's as is done when using e.stopImmediatePropagation();, but not have to use it.
To emulate problem: Click the Apple or Google logo (or Bell Icon) and then click it
again. The solution should remove .active from it's associated
.modal and it should close just like it does when clicking document (except for Bell Icon button which isn't set up to close when document is clicked). I just don't know how to acheive this without using e.stopImmediatePropagation();
$("[data-close]").click(function(e) {
const dataClose = $(this).attr("data-close");
const elem = $('[data-id="' + dataClose + '"]').length ?
$('[data-id="' + dataClose + '"]') :
$(dataClose);
if (elem.hasClass("active") && elem.is(":visible")) {
elem.removeClass("active");
/* e.stopImmediatePropagation();*/
}
});
$(".button").on("click", function() {
const id = $(this).prop("id");
$(".modal").each(function() {
$(this).toggleClass("active", $(this).data("id") == id);
});
});
$(document).on("click", function(e) {
if (
$(".apple-modal, .google-modal").hasClass("active") &&
!$(".modal, .modal *, .button").is(e.target)
) {
$(".modal").removeClass("active");
}
});

I was able to implement what you want by adding the close modal functionality inside the click button and check if the modal for the current element is visible or not:
$(".button").on("click", function () {
const dataClose = $(this).attr("data-close");
const elem = $('[data-id="' + dataClose + '"]').length
? $('[data-id="' + dataClose + '"]')
: $(dataClose);
if (elem.hasClass("active") && elem.is(":visible")) {
elem.removeClass("active");
} else {
const id = $(this).prop("id");
$(".modal").each(function () {
$(this).toggleClass("active", $(this).data("id") == id);
});
}
});
$(document).on("click", function (e) {
if (
$(".apple-modal, .google-modal").hasClass("active") &&
!$(".modal, .modal *, .button").is(e.target)
) {
$(".modal").removeClass("active");
}
});
.buttons {
display: flex;
align-items: center;
}
.button {
height: 30px;
cursor: pointer;

how come drillmenu doesn't work and the screens overlap?

I have a problem with the code of this drillmenu. When I click on the "click" button the menu overlaps and the other screen items appear.
I have to add many other buttons and submenus, but in this way I will never be able to do it. I was inspired by a menu on the web, but I just can't!
enter code here
<div class="wrapper">
<ul data-drilldown>
<li><a data-drilldown-item href="#">Home</a></li>
<li><a href="#" data-drilldown-button>Contact ➤
<ul data-drilldown-sub>
<a href="#" data-drilldown-back>← Back</a>
<li>house</li>
<li><a href="#" data-drilldown-button-2>More ➤
<ul data-drilldown-sub-2>
<a href="#" data-drilldown-back-2>← Back</a>
<li><a href="">personal</a></li>
</ul>
</a> </li>

</a> </li>
<li><a href="#" data-drilldown-button>click ➤

My Fiddle

I checked your code and looked in the console of the browser; it has one jQuery error like $ is not defined. I think you forget to add jQuery library; that's the way this error occurs. Add jQuery file or you can use jQuery cdn also like this.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
Add this line add before the </body> tag and then check if it works.

</nav>
And this is what I tried to do.
if (window.addEventListener) {
var keys = "16";
window.addEventListener("keydown", function(e) {
keys.push(e.keyCode);
if (keys.toString() >= 0) {
document.getElementById("about").hover();
};
});
};
