A menu is a component that consists of two parts, the menu item link that opens the menu and the menu container itself. Menus are not rendered on printable pages.

Root Menu

Menu components that are placed inside a menuBar are called root menus. The menu item links are placed horizontally across the menuBar. When the menu item link is selected, the menu container (typically) opens underneath the menu item link.

Submenu

Menu components that are placed inside another menu component are called submenus. The submenu item links are placed vertically inside the parent menu. When the submenu item link is selected, the submenu container (typically) opens to the right of the submenu item link. There is no enforced maximum depth to the level of submenu nesting, although it is generally considered a good UI practice to limit nested menus to no more than 3 levels deep.

Popup Menu

A menu component can also be placed directly inside a popup component. This is called a menu popup. In the case of a menu popup, the menu component does not provide the menu item link. In otherwords, the text attribute of the menu does not appear anywhere on the page. Instead, you would create another command type component (like a commandLink or commandButton) that would be set to open the menu popup.

Menu Content

Menus are designed to contain child menu, commandMenuItem, and goMenuItem components. These children can be grouped using the group component, which results in separator lines being created around each group. You may also include a facetRef, iterator, or switcher in a menu if these wrappers provide components that would normally belong in the menu.

Code Example(s)

<af:menuBar>
  <af:menu text="root menu">
    <af:menu text="submenu">
      <af:commandMenuItem text="Submenu Item"/>
    </af:menu>  
    <af:group>
      <af:commandMenuItem text="Item1"/>
      <af:commandMenuItem text="Item2"/>
      <af:commandMenuItem text="Item3"/>
    </af:group>
    <af:group>
      <af:goMenuItem text="GoItem1"/>
      <af:goMenuItem text="GoItem2"/>
      <af:goMenuItem text="GoItem3"/>
    </af:group>
  </af:menu>  

<af:popup id="popupMenu">
  <af:menu>
    <af:commandMenuItem text="Item1"/>
    <af:commandMenuItem text="Item2"/>
    <af:commandMenuItem text="Item3"/>
  </af:menu>
</af:popup>

Attributes

Name	Type	Supports EL?	Description
accessKey	char	Yes	a character used to gain quick access to this menu. For accessibility reasons, this functionality is not supported in screen reader mode. If the same access key appears in multiple input fields in the same page of output, the rendering user agent will cycle among the elements accessed by the similar keys. Note that user agents are inconsistent about dealing with two links having same access key, and so the cycling behavior is dependent on what the user agent provides. This attribute is sometimes referred to as the "mnemonic". The character specified by this attribute must exist in the `Text` attribute of this button instance. If it does not, the user will receive no visual indication of the existence of the accessKey. The easiest, and most convenient way to specify both the text and the mnemonic together is to use textAndAccessKey. Note that the accessKey is triggered by browser-specific and platform-specific modifier keys. It even has browser-specific meaning. For example, Internet Explorer 7.0 will set focus when you press Alt+<accessKey>. Firefox 2.0 on some operating systems you press Alt+Shift+<accessKey>. Firefox 2.0 on other operating systems you press Control+<accessKey>. Refer to your browser's documentation for how it treats accessKey. Beyond normal type menu access key behavior, menus and commandMenuItems support menu-type access key behavior when the focus is currently in a menu or menuBar. Menu-type access key behavior allows access to contained menus, submenus, and commandMenuItems without the need for any keyboard modifiers. When the focus is inside a menu or menuBar, you can simply press the accessKey, without modifiers, for a menu or commandMenuItem accessible within the menu or menuBar to immediately move focus to that menu item.
attributeChangeListener	javax.el.MethodExpression	Only EL	a method reference to an attribute change listener. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.
binding	oracle.adf.view.rich.component.rich.RichMenu	Only EL	an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.
clientComponent	boolean	Yes	Default Value: false whether a client-side component will be generated. A component may be generated whether or not this flag is set, but if client Javascript requires the component object, this must be set to true to guarantee the component's presence. Client component objects that are generated today by default may not be present in the future; setting this flag is the only way to guarantee a component's presence, and clients cannot rely on implicit behavior. However, there is a performance cost to setting this flag, so clients should avoid turning on client components unless absolutely necessary.
contentDelivery	String	Yes	Valid Values: immediate, lazy Default Value: immediate whether the menu content is delivered with the initial page. When contentDelivery is "immediate", the content is inlined into the initial page. If contentDelivery is "lazy", the menu's content will be delivered to the client only after the first request to show that menu. By default, contentDelivery is immediate, which means the menu content will be sent to the client on initial rendering. Note that for a menu popup (a menu component placed directly inside a popup component) both the menu and the popup have a content delivery setting. In this case the popup's contentDelivery setting has precedence, and the menu's content delivery setting is ignored.
customizationId	String	Yes	This attribute is deprecated. The 'id' attribute should be used when applying persistent customizations. This attribute will be removed in the next release.
detachable	boolean	Yes	Default Value: false whether the item is detachable.
disabled	boolean	Yes	Default Value: false whether the menu should be disabled.
icon	String	Yes	the URI of an image to be displayed on the menu item. This attribute supports these various types of URIs: absolute - an absolute path to the image, like "http://oracleimg.com/admin/images/ocom/hp/oralogo_small.gif" relative - a path located relatively to the source page, like "bullet.jpg" context relative - a path relatively based on the web application's context root, like "/images/error.png" server relative - a path relatively based on the web server by application name, like "//adf-richclient-demo-context-root/images/error.png" As icon does not allow alternative text to be provided for the image, in order to create an accessible product icon must only be used when its use is purely decorative.
id	String	No	the identifier for the component. The identifier must follow a subset of the syntax allowed in HTML: Must not be a zero-length String. First character must be an ASCII letter (A-Za-z) or an underscore ('_'). Subsequent characters must be an ASCII letter or digit (A-Za-z0-9), an underscore ('_'), or a dash ('-').
inlineStyle	String	Yes	the CSS styles to use for this component. This is intended for basic style changes. The inlineStyle is a set of CSS styles that are applied to the root DOM element of the component. If the inlineStyle's CSS properties do not affect the DOM element you want affected, then you will have to create a skin and use the skinning keys which are meant to target particular DOM elements, like ::label or ::icon-style.
partialTriggers	String[]	Yes	the IDs of the components that should trigger a partial update. This component will listen on the trigger components. If one of the trigger components receives an event that will cause it to update in some way, this component will request to be updated too. Identifiers are relative to the source component (this component), and must account for NamingContainers. If your component is already inside of a naming container, you can use a single colon to start the search from the root of the page, or multiple colons to move up through the NamingContainers - "::" will pop out of the component's naming container (or itself if the component is a naming container) and begin the search from there, ":::" will pop out of two naming containers (including itself if the component is a naming container) and begin the search from there, etc.
rendered	boolean	Yes	Default Value: true whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client). If you want to change a component's rendered attribute from false to true using PPR, set the partialTrigger attribute of its parent component so the parent refreshes and in turn will render this component.
shortDesc	String	Yes	the short description of the component. This text is commonly used by user agents to display tooltip help text, in which case the behavior for the tooltip is controlled by the user agent, e.g. Firefox 2 truncates long tooltips. For form components, the shortDesc is displayed in a note window. For components that support the helpTopicId attribute it is recommended that helpTopicId is used as it is more flexible and is more accessibility-compliant.
styleClass	String	Yes	a CSS style class to use for this component. The style class can be defined in your jspx page or in a skinning CSS file, for example, or you can use one of our public style classes, like 'AFInstructionText'.
text	String	Yes	the text of the item
textAndAccessKey	String	Yes	an attribute that will simultaneously set both the "text" and "accessKey" attributes from a single value, using conventional ampersand ('&') notation. For example, setting this attribute to "T&ext" will set the text to "Text" and the access key to 'e'.
unsecure	java.util.Set	Yes	A whitespace separated list of attributes whose values ordinarily can be set only on the server, but need to be settable on the client. Currently, this is supported only for the "disabled" attribute.
visible	boolean	Yes	Default Value: true the visibility of the component. If it is "false", the component will be hidden on the client. Unlike "rendered", this does not affect the lifecycle on the server - the component may have its bindings executed, etc. - and the visibility of the component can be toggled on and off on the client, or toggled with PPR. When "rendered" is false, the component will not in any way be rendered, and cannot be made visible on the client. In most cases, use the "rendered" property instead of the "visible" property.
