I want to add a custom right-click menu to my web application. Can this be done without using any pre-built libraries? If so, how to display a simple custom right-click menu

I use something similar to the following jsfiddle

function onright(el, cb) {
    //disable right click
    document.body.oncontextmenu = 'return false';
    el.addEventListener('contextmenu', function (e) { e.preventDefault(); return false });
    el.addEventListener('mousedown', function (e) {
        e = e || window.event;
        if (~~(e.button) === 2) {
            if (e.preventDefault) {
                e.preventDefault();
            } else {
                e.returnValue = false;
            }
            return false;
        }
    });

    // then bind Your cb
    el.addEventListener('mousedown', function (e) {
        e = e || window.event;
        ~~(e.button) === 2 && cb.call(el, e);
    });
}

if You target older IE browsers you should anyway complete it with the ' attachEvent; case

<script language="javascript" type="text/javascript">
  document.oncontextmenu = RightMouseDown; 
  document.onmousedown = mouseDown; 

  function mouseDown(e) {
    if (e.which==3) {//righClick
      alert("Right-click menu goes here");
    } 
  }

  function RightMouseDown() { 
    return false; 
  }
</script>
</body> 
</html>

<html>
<head>
<style>
.rightclick {
    /* YOUR CONTEXTMENU'S CSS */
    visibility: hidden;
    background-color: white;
    border: 1px solid grey;
    width: 200px;
    height: 300px;
}
</style>
</head>
<body>
  <div class="rightclick" id="ya">
    <p onclick="alert('choc-a-late')">I like chocolate</p><br><p onclick="awe-so-me">I AM AWESOME</p>
  </div>
  <p>Right click to get sweet results!</p>
</body>
<script>
    document.onclick = noClick;
    document.oncontextmenu = rightClick;
    function rightClick(e) {
        e = e || window.event;
        e.preventDefault();
        document.getElementById("ya").style.visibility = "visible";
        console.log("Context Menu v1.3.0 by IamGuest opened.");
   }
function noClick() {
    document.getElementById("ya").style.visibility = "hidden";
    console.log("Context Menu v1.3.0 by IamGuest closed.");
}
</script>

You can tweak and modify this code to make a better looking, more efficient contextmenu. As for modifying an existing contextmenu, I'm not sure how to do that... Check out this fiddle for an organized point of view. Also, try clicking the items in my contextmenu. They should alert you a few awesome messages. If they don't work, try something more... complex.

Simplest jump start function, create a context menu at the cursor position, that destroys itself on mouse leave.

oncontextmenu = (e) => {
  e.preventDefault()
  let menu = document.createElement("div")
  menu.id = "ctxmenu"
  menu.style = `top:${e.pageY}px;left:${e.pageX}px`
  menu.onmouseleave = function(){ctxmenu.outerHTML=''}
  menu.innerHTML = "<p>Option1</p><p>Option2</p><p>Option3</p><p>Option4</p><p onclick='alert(`Thank you!`)'>Upvote</p>"
  document.body.appendChild(menu)
}

#ctxmenu {
  position: fixed;
  background:ghostwhite;
  color: black;
  cursor: pointer;
  border: 1px black solid
}

#ctxmenu > p {
  padding: 0 1rem;
  margin: 0
}

#ctxmenu > p:hover {
  background: black;
  color: ghostwhite
}
