-
-`paper-dropdown-menu` works together with `paper-dropdown` and `core-menu` to
-implement a drop-down menu. 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` will be used as the drop-down
-menu. It should be a `paper-dropdown` or other overlay element. You should
-also provide a `core-selector` or other selector element, such as `core-menu`,
-in the drop-down. You should apply the class `menu` to the selector element.
-
-Example:
-
-    <paper-dropdown-menu label="Your favorite pastry">
-        <paper-dropdown class="dropdown">
-            <core-menu class="menu">
-                <paper-item>Croissant</paper-item>
-                <paper-item>Donut</paper-item>
-                <paper-item>Financier</paper-item>
-                <paper-item>Madeleine</paper-item>
-            </core-menu>
-        </paper-dropdown>
-    </paper-dropdown-menu>
-
-This example renders a drop-down menu with 4 options.
