+/**
+ * @name MenuToggle
+ * @description
+ * The `menuToggle` directive can be placed on any button to toggle a menu open or closed.
+ * If it is added to the [NavBar](../../nav/NavBar) of a page, the button will only appear
+ * when the page it's in is currently a root page. See the [Menu Navigation Bar Behavior](../Menu#navigation-bar-behavior)
+ * docs for more information.
+ *
+ *
+ * @usage
+ *
+ * A simple `menuToggle` button can be added using the following markup:
+ *
+ * ```html
+ * <button menuToggle>Toggle Menu</button>
+ * ```
+ *
+ * To toggle a certain menu by its id or side, give the `menuToggle`
+ * directive a value.
+ *
+ * ```html
+ * <button menuToggle="right">Toggle Right Menu</button>
+ * ```
+ *
+ * @demo /docs/v2/demos/menu/
