The major aim of this tutorial is to cover the main menu components that get used with Primefaces implementation. Typically, a huge amount of applications spread over internet use a different form of menus. This tutorial will cover the following types of menu:
Let’s get started explaining all of these menu types to see all of those featured functionalities that Primefaces provide for this kind of components.
Tag | menu |
---|---|
Component Class | org.primefaces.component.menu.Menu |
Component Type | org.primefaces.component.Menu |
Component Family | org.primefaces.component |
Renderer Type | org.primefaces.component.MenuRenderer |
Renderer Class | org.primefaces.component.menu.MenuRenderer |
Name | Default | Type | Description |
---|---|---|---|
id | null | String | Unique identifier of the component. |
rendered | true | Boolean | Boolean value to specify the rendering of the component, when set to false component will not be rendered. |
binding | null | Object | An el expression that maps to a server side UIComponent instance in a backing bean. |
widgetVar | null | String | Name of the client side widget. |
model | null | MenuModel | A menu model instance to create menu programmatically. |
trigger | null | String | Target component to attach the overlay menu. |
my | null | String | Corner of menu to align with trigger element. |
at | null | String | Corner of trigger to align with menu element. |
overlay | false | Boolean | Defines positioning type of menu, either static or overlay. |
style | null | String | Inline style of the main container element. |
styleClass | null | String | Style class of the main container element. |
triggerEvent | click | String | Event to show the dynamic positioned menu. |
A menu is composed of submenus and menuitems. Submenus are used to group menuitems, while menuitems correspond to those actions required. Following example shows you the most simplest use of Menu component. index.xhtml

Menu can be positioned in two ways; static or dynamic. Static position means that the menu is in normal page flow. In contrast dynamic menus isn’t in the normal flow of the page allowing them to overlay other elements. For defining menu dynamically, you should pass through below steps:
index1.xhtml
<html xmlns="https://www.w3.org/1999/xhtml"
xmlns:ui="https://java.sun.com/jsf/facelets"
xmlns:h="https://java.sun.com/jsf/html"

xmlns:p="https://primefaces.org/ui">

<h:form>
<p:menu overlay="true" trigger="triggerButton" my="left top" at="right top">
<p:submenu label="File">
<p:menuitem value="Open"></p:menuitem>
<p:menuitem value="Edit"></p:menuitem>
<p:separator/>
<p:menuitem value="Exit"></p:menuitem>
</p:submenu>
<p:submenu label="Help">
<p:menuitem value="About Primefaces"></p:menuitem>
<p:menuitem value="Contact Us"></p:menuitem>
<p:separator/>
<p:menuitem value="Help"></p:menuitem>
</p:submenu>
</p:menu>
<p:commandButton id="triggerButton" value="Trigger Menu"></p:commandButton>
</h:form>
</html>
As now, you’ve developed a simple static menu and more complicated dynamic one. Both of these menus are containing menuitems that correspond to required actions that menu aim to provide. Those menuitems are actually actions likewise p:commandButton, so it’s also applicable for you to ajaxify them. index2.xhtml

public class MenuManagedBean {

}
}
Menus can be created programmatically as well, this is more flexible compared to the declarative approach. You can define like that menu by using org.primefaces.model.MenuModel instance. Components like p:submenu, p:menuitem and p:separator have also their default implementation that are used for define programmatic menu. Following example shows you the same business scenario that you’ve developed before, this time the menu will be rendered programmatically. index3.xhtml

Menubar is a horizontal navigation component.

Similar to Menu component, Menubar requires p:submenu and p:menuitem as a child to compose the menubar.
Menubar supports nested menus, that is by providing a submenus within another parent submenus. index5.xhtml

<p:separator/>
<p:menuitem value="Help"></p:menuitem>
</p:submenu>
</p:menubar>
</h:form>

Menubar has also supported rooted menuitem, that is by providing a direct p:menuitem child component within p:menubar. index6.xhtml

</p:menubar>
</h:form>
</html>
Likewise p:commandButton component, p:menuitem has also supported ajaxifying actions. You’ve already experienced this in p:menu section. You can use p:menuitem for doing actions - Ajax and Non-Ajax - and navigation as well. Following sample shows you the different usage of p:menuitem. index7.xhtml

TieredMenu consists of submenus and menuitems, submenus can be nested and each nested submenu will be displayed in an overlay. Those menuitems that get involved within p:tieredMenu component are targeted for Ajax, non-Ajax and navigation actions like all of these menuitems used previously. Following example shows you the most simplest applicable use for p:tieredMenu that is containing for a set of mixed actions. index11.xhtml

By default, submenus are displayed when mouse is over root menuitems, set autoDisplay to false require a click on root menuitems to enable autoDisplay mode. The same example will be used to set autoDisplay to false against p:tieredMenu component.
Likewise Menu component, TieredMenu can also be overlaid using the same way that is used for overlaying the Menu component (See Menu Overlay). index11.xhtml
