Instance Method Summary
	`addArrow_(?goog.ui.SubMenu subMenu, ?Element element)` Appends a child node with the class goog.getCssName('goog-submenu-arrow') or 'goog-submenu-arrow-rtl' which can be styled to show an arrow.
	`createDom(?goog.ui.SubMenu subMenu) ⇒ ?Element` Overrides {@link goog.ui.MenuItemRenderer#createDom} by adding the additional class 'goog-submenu' to the created element, and passes the element to {@link goog.ui.SubMenuItemRenderer#addArrow_} to add an child element that can be styled to show an arrow.
	`decorate(?goog.ui.SubMenu subMenu, ?Element element) ⇒ ?Element` Overrides {@link goog.ui.MenuItemRenderer#decorate} by adding the additional class 'goog-submenu' to the decorated element, and passing the element to {@link goog.ui.SubMenuItemRenderer#addArrow_} to add a child element that can be styled to show an arrow. Also searches the element for a child with the class goog-menu. If a matching child element is found, creates a goog.ui.Menu, uses it to decorate the child element, and passes that menu to subMenu.setMenu.
	`initializeDom(?goog.ui.SubMenu subMenu)` Overrides {@link goog.ui.MenuItemRenderer#initializeDom} to tweak the DOM structure for the span.goog-submenu-arrow element depending on the text direction (LTR or RTL). When the SubMenu is RTL the arrow will be given the additional class of goog-submenu-arrow-rtl, and the arrow will be moved up to be the first child in the SubMenu's element. Otherwise the arrow will have the class goog-submenu-arrow-ltr, and be kept as the last child of the SubMenu's element.

Static Method Summary
