Here is an example of using the Menu Button in a plain html page:
<html>
<head>
<link href="https://developer.temenos.com/uux/base.css" rel="stylesheet" />
<script src="https://developer.temenos.com/uux/unified-ux-web.min.js"></script>
</head>
<body>
<uwc-menu-button icon="star_outline"></uwc-menu-button>
<script>
const menuBtn = document.querySelector("uwc-menu-button");
const menuItems = [
{
label: "Account balance",
action: () => alert("Your account balance is: $1,000,000"),
},
{
label: "Create new account",
},
];
menuBtn.menuItems = menuItems;
</script>
</body>
</html>
