##<paper-menu-button>

Material design: [Dropdown buttons](https://www.google.com/design/spec/components/buttons.html#buttons-dropdown-buttons)

`paper-menu-button` allows one to compose a designated "trigger" element with
another element that represents "content", to create a dropdown menu that
displays the "content" when the "trigger" is clicked.

The child element with the class `dropdown-trigger` will be used as the
"trigger" element. The child element with the class `dropdown-content` will be
used as the "content" element.

The `paper-menu-button` is sensitive to its content's `iron-select` events. If
the "content" element triggers an `iron-select` event, the `paper-menu-button`
will close automatically.

Example:

```html

  
  
    Share
    Settings
    Help
  

```
