How to make a dropdown menu transition with CSS?

I have created a responsive navigation-bar/menu but I want it to appear with a sliding animation from the top to the bottom when the needed button is presed. The menu does appear on itself but it completely ignores the transitioni have set it to execute. I tried multiple methods - using webkit library, using the change in height method, etc. It appears that none of them work with my code. If anyone can help, please reach to me.

const toggleButton = document.querySelector('.dot_a');
const navbarLinks = document.querySelector('.nav-list');

toggleButton.addEventListener('click', () => {
  navbarLinks.classList.toggle('active')
})
body {
  background-color: black;
  background-size: cover;
  background-repeat: no-repeat;
  background-attachment: fixed;
  font-family: Arial, Helvetica, sans-serif;
  font-weight: bold;
  margin: 0;
}

.pro_column1 {
  width: 15%;
}

.pro_column2 {
  width: 85%;
}

.nav {
  overflow: hidden;
  background-color: white;
  /*opacity: 60%;*/
  margin: 10px;
  border-radius: 10px;
  width: 850px;
  /*background:#3c6382;
  /*box-shadow:0px 5px 20px rgba(0,0,0,0.1);*/
  /*border: solid black 2px;*/
}



.nav a {
  color: #747d8c;
  text-align: center;
  padding: 27px 10px;
  text-decoration: none;
  font-size: 17px;
  margin: 0;
  border-radius: 10px;
  transition: 1s;
}

.nav a:hover {
  background-color: #ddd;
  color: black;
  -webkit-animation: 1s ease-in forwards;
}

.dot_a {
  padding: 25px 10px;
  font-size: 17px;
  text-align: center;
  margin: 0;
  display: inline-block;
  border-radius: 10px;
  transition: 1s;

  -webkit-user-select: none;
  -khtml-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  -o-user-select: none;
  user-select: none;
}

i {
  /*float: right;*/
  font-size: 20px;
  border: none;
  outline: none;
  color: #747d8c;
  padding: 25px 5px;
  font-family: inherit;
  margin: 0px;
  border-radius: 20px;
  transition: 1s;
}

.dot {
  height: 15px;
  width: 15px;
  border-radius: 50%;
  display: inline-block;
  margin: 0px;
}

.column {
  float: left;
  width: 33.33%;
  padding: 10px;
  height: 300px;
}

.row:after {
  content: "";
  display: table;
  clear: both;
}

@media screen and (max-width: 870px) {
  .nav a {
    padding-top: 5px;
    padding-bottom: 5px;
    display: block;

    
    
  }
  .dot_a {
    padding-top: 3px;
    padding-bottom: 0px;
  }
  .nav {
    width: 90%;
    
    
  }
  .dot {
    margin-top: 15px;
    margin-bottom: 15px;
  }


  .nav-list{  
    display: none;
    max-height: 0;
    -webkit-animation: slide-in-top 0.5s cubic-bezier(0.250, 0.460, 0.450, 0.940) both;
    animation: slide-in-top 0.5s cubic-bezier(0.250, 0.460, 0.450, 0.940) both;


  }

  .nav-list.active {
    display: block;
    margin: 0;
    padding: 0; 
    max-height: fit-content;
    -webkit-animation: slide-in-top 0.5s cubic-bezier(0.250, 0.460, 0.450, 0.940) both;
    animation: slide-in-top 0.5s cubic-bezier(0.250, 0.460, 0.450, 0.940) both;

  
  }

}

@-webkit-keyframes slide-in-top {
  0% {
    -webkit-transform: translateY(-1000px);
            transform: translateY(-1000px);
    opacity: 0;
  }
  100% {
    -webkit-transform: translateY(0);
            transform: translateY(0);
    opacity: 1;
  }
}
@keyframes slide-in-top {
  0% {
    -webkit-transform: translateY(-1000px);
            transform: translateY(-1000px);
    opacity: 0;

A easy way to do it is with CSS, for this cases i always use Animista. Try adding this to your CSS file and then add the class slide-in-top to your menu container.

.slide-in-top {
-webkit-animation: slide-in-top 0.5s cubic-bezier(0.250, 0.460, 0.450, 0.940) both;
        animation: slide-in-top 0.5s cubic-bezier(0.250, 0.460, 0.450, 0.940) both;
}


@-webkit-keyframes slide-in-top {
  0% {
    -webkit-transform: translateY(-1000px);
            transform: translateY(-1000px);
    opacity: 0;
  }
  100% {
    -webkit-transform: translateY(0);
            transform: translateY(0);
    opacity: 1;
  }
}
@keyframes slide-in-top {
  0% {
    -webkit-transform: translateY(-1000px);
            transform: translateY(-1000px);
    opacity: 0;
  }
  100% {
    -webkit-transform: translateY(0);
            transform: translateY(0);
    opacity: 1;
  }
}
