Feature Request: Add key-prop to MenuItem

[nimo23]

Please add the prop key to the MenuItem so that react can render based on the key:

/**
 * Defines model of MenuItem API.
 * @group Model
 */
export interface MenuItem {
   // TODO add key prop:
   /**
     * Unique key of the node.
     */
    key?: string | number | undefined;

    /**
     * Unique identifier of the menuitem.
     */
    id?: string | undefined;
    /**
     * Text of the menuitem.
     */
    label?: string | undefined;

Menu's should already be rendering by a unique key the menu creates. Are you not seeing that or is there a bug?

I can't see PrimeReact automatically generating a unique key for a menu item. By the way, I usually expect the key-prop to be assigned by the user (since he knows which key to choose). I expect something like this:

const userNode: MenuItem = {
	id: user.id,
	key: user.id, // cannot set key as Interface MenuItem does not have a key prop
	label: user.username,
	expanded: true,
	data: {
	    name: user.username,
	},
	items: []
};

But the key is just used by react for uniqueness and the component gaurantees that. What are you using key for? That is what the data element of the menu is for so you can add any metadata you want.
