PolymerJS：如何安装paper-submenu？

Question

I'd like to try out the paper-submenu element .

But I can't find the bower-command to install the element. The page of the paper-submenu is here:

https://elements.polymer-project.org/elements/paper-menu

But the command

bower install --save PolymerElements/paper-menu

does not install the paper-submenu along.

and just using

bower install --save PolymerElements/paper-submenu

does throw an error.

Where do I get the paper-submenu element?

---

Update

It was suggested to just install the paper-menu element via bower. I believe that I made it clear that I did exactly this with the commands I posted above.

Here are some screenshots of my folder structure so that you can see what gets installed when I install the paper-menu element through the above bower command:

**As you can see there is NO paper-submenu element installed along

Answer 1

如果你看一下git repo的paper-menu你会看到paper-submenu的文件也在那里，所以要使用paper-submenu你只需要安装paper-menu并导入为<link rel="import" href="bower_components/paper-menu/paper-submenu.html">

Answer 2

You should import paper-menu element , it's coming with paper-submenu, here is a code pen example. I used polygit for my imports in code pen settings paper-submenu example
