-
-Material design: [Dropdown menus](https://www.google.com/design/spec/components/buttons.html#buttons-dropdown-buttons)
-
-`paper-dropdown-menu` is similar to a native browser select element.
-`paper-dropdown-menu` works with selectable content. The currently selected
-item is displayed in the control. If no item is selected, the `label` is
-displayed instead.
-
-The child element with the class `dropdown-content` will be used as the dropdown
-menu. It could be a `paper-menu` or element that triggers `iron-select` when
-selecting its children.
-
-Example:
-
-```html
-<paper-dropdown-menu label="Your favourite pastry">
-  <paper-menu class="dropdown-content">
-    <paper-item>Croissant</paper-item>
-    <paper-item>Donut</paper-item>
-    <paper-item>Financier</paper-item>
-    <paper-item>Madeleine</paper-item>
-  </paper-menu>
-</paper-dropdown-menu>
-```
-
-This example renders a dropdown menu with 4 options.
-
-Similarly to using `iron-select`, `iron-deselect` events will cause the
-current selection of the `paper-dropdown-menu` to be cleared.
-
-### Styling
-
-The following custom properties and mixins are also available for styling:
-
-| Custom property | Description | Default |
-| --- | --- | --- |
-| `--paper-dropdown-menu` | A mixin that is applied to the element host | `{}` |
-| `--paper-dropdown-menu-disabled` | A mixin that is applied to the element host when disabled | `{}` |
-| `--paper-dropdown-menu-ripple` | A mixin that is applied to the internal ripple | `{}` |
-| `--paper-dropdown-menu-button` | A mixin that is applied to the internal menu button | `{}` |
-| `--paper-dropdown-menu-input` | A mixin that is applied to the internal paper input | `{}` |
-| `--paper-dropdown-menu-icon` | A mixin that is applied to the internal icon | `{}` |
-
-You can also use any of the `paper-input-container` and `paper-menu-button`
-style mixins and custom properties to style the internal input and menu button
-respectively.
