I’m trying to put a vaadin-vertical-layout inside a popup-container, but calling popup results in an error:
<vcf-popup id="popup" for="myComboBox">
<template>
<style>
[part="container"]
{
background-color: green;
}
</style>
<div part="container">
<vaadin-vertical-layout id="popupContent"><span></span></vaadin-vertical-layout>
</div>
</template>
</vcf-popup>
