+
+`paper-menu-button` works together with a button and a `paper-dropdown` to
+implement a button that displays a drop-down when tapped on.
+
+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.
+
+Example:
+
+    <paper-menu-button>
+        <paper-icon-button icon="menu" noink></paper-icon-button>
+        <paper-dropdown class="dropdown">
+            <core-menu class="menu">
+                <paper-item>Share</paper-item>
+                <paper-item>Settings</paper-item>
+                <paper-item>Help</paper-item>
+            </core-menu>
+        </paper-dropdown>
+    </paper-menu-button>
