+/**
+ * core-menu-button is a core-icon-button with a drop down menu
+ * that allows the user to select an option. The drop down menu is styled with
+ * an arrow pointing to the button, and can be positioned to the top or the
+ * bottom of the button with the valign property. The valign property aligns
+ * the menu to the left or right edge of the button.
+ *
+ * Example:
+ *
+ *     <core-menu-button selected="0">
+ *       <core-item icon="settings" label="Settings"></core-item>
+ *       <core-item icon="dialog" label="Dialog"></core-item>
+ *       <core-item icon="search" label="Search"></core-item>
+ *     </core-menu-button>
+ *
+ * @class core-menu-button
