javascript - How can I make searchbox appear in my navbar?

Question

I'm designing my website, and I started with navbar, which looks very much like Apple's one, because I like that one a lot. But I ran in some problems here and there, but the biggest one I have right now is SearchBox. I designed it, and it looks good, but when I manage to code JavaScript to enable it when the little search button is clicked, it appears to be really messed up. Does someone know how can I fix that? Also, how can I add animation when it appears (also for navbar items) and change the background of header? Look at https://www.apple.com/ up in navigation to know what I mean. Here are my HTML, CSS and JS codes.

const selectElement = (element) => document.querySelector(element);

selectElement('.mobile-menu').addEventListener('click', () => {
    selectElement('header').classList.toggle('active');
});

The easiest way to accomplish what you want to do is with jQuery.

The jQuery is there... I could get some of the css fixed... I am having a little bit of trouble with putting the search bar contents on the same line...

I had to comment out the css for .nav-link-search, because the image didn't exist.

delay = 50;
const selectElement = (element) => document.querySelector(element);

selectElement('.mobile-menu').addEventListener('click', () => {
    selectElement('header').classList.toggle('active');
});

//for hiding nav menu items and displaying the search bar
$(".nav-link-search").click(function() {
  size = $(".nav-item").length;
  $('.nav-item').each(function(i) {
    $(this).delay(delay * (size - i)).animate({opacity: 0, display: "none"}, delay);
  });
  $(".searchbox").show((size + 2) * delay);
});

//for hiding the search bar and displaying the nav menu items
$(".close-btn").click(function() {
  $(".searchbox").hide();
  $('.nav-item').each(function(i) {
    $(this).delay(delay * i).animate({opacity: 1, display: "inline-block"}, delay);
  });
});
