About this version
vwc-menu is a surfacing menu component, showing up on demand, eg upon user action.
vwc-menu fetured with an internal list, while all LightDOM elements of it become children of that list.
This component is an extension of <mwc-menu>.
Usage example:
<vwc-menu>
<vwc-list-item>Item 1</vwc-list-item>
<vwc-list-item>Item 2</vwc-list-item>
<vwc-list-item>Item 3</vwc-list-item>
<vwc-list-item>Item 4</vwc-list-item>
</vwc-menu>vwc-list-item should be used for the menu items, putting any of you custom content within, including rich HTML if needed.
It is still consumer's responsibility to initiate
vwc-list-item, as any other Vivid component.
Initiate vwc-menu to be available in your component/application:
import '@vonage/vwc-menu';
// or, to be able to use casting in TypeScript, do
import { VWCMenu } from '@vonage/vwc-menu';
import '@vonage/vwc-list/vwc-list-item.js';vwc-menu exposes several APIs to provide its fuctionality, namely properties, methods and events.

Using the menu's fixed or absolute properties will position the menu relative to the window or ancestor (absolute/relative) element respectively.
If the menu doesn't show up in the right position, make sure that an ancestor element exists and positioned correctly, and that an anchor property is defined, along with corner and menuCorner. For more information, please refer to MWC's documentation where you can find a live demo.
