How to make this dropdown work using flexbox?-CodePudding

I am trying to make this dropdown button using flexbox but it's not working as I want. It's not displaying when I hover around the button using display properties. Can someone edit this code so that the dropdown menu works?

Is this what you want

function Enable(){
    x = document.getElementById("Ulist");
    if(x.className == "display"){
   x.className  = " active";
   }else{
   x.className == "display";
   }
}

li{
  list-style: none;
  
}

.Maincover{
   display: flex;
   flex-direction: column;

   align-items: center;
   height: 300px;
}


button{
 font-family: montserrat;
 font-weight: 500;
 width: 100px;
 border-radius: 5px;
 color: white;
 border: 0px;
 padding: 5px 10px;
 text-align: center;
 background-color: tomato;

}

.list{
  font-family: rubik;
  text-align: center;
  margin-top: 10px;

}
.display{
  padding:0px;
  display: none;
}

.display.active{
  display: block;
}
.hoverbutton:hover ~ .display{
 display: block;
}

<div >
<button  onclick="Enable()">Hover Here</button>
<ul  id="Ulist">
<li  id="lists">List item 1</li>
<li  id="lists">List item 2</li>
<li  id="lists">List item 3</li>
</ul>
</div>
