Polymer paper-menu with Angular2

问题

I'm trying to user Polymer v1.0 elements with Angular2 beta3 and I'm having issues. Some elements work fine, such as input boxes.

However, when I try and use paper-menu or paper-dropdown-menu it doesn't work.

How can I get this plnkr to work?

回答1:

You have to import all the elements you're using.

The imports were missing for

paper-item
paper-listbox

I also think it's important to import full polyfills

<script src="https://cdn.rawgit.com/download/polymer-cdn/1.1.4/lib/webcomponentsjs/webcomponents.js"></script>

instead of lite

    <script src="https://cdn.rawgit.com/download/polymer-cdn/1.1.4/lib/webcomponentsjs/webcomponents-lite.js"></script>

Plunker example of the fixed example.
