RichFaces Rich: PanelMenu

RichFaces is a popular open-source library for building rich, responsive and interactive web applications. One of the core components of RichFaces is the Rich: PanelMenu which provides an easy-to-use navigation menu for web applications.

Features

The Rich: PanelMenu component comes with a wide range of features including:

• Multiple levels of navigation
• Built-in AJAX support for quick and responsive navigation
• Customizable skins and themes
• Support for icons and custom labels
• Integration with other RichFaces components
• Accessibility support for keyboard and screen reader users

Getting Started

To start using the Rich: PanelMenu component in your web application, you need to add the RichFaces library to your project. You can download the library from the RichFaces website or use a dependency manager like Maven or Gradle.

Once you have added the library, you can start adding the Rich: PanelMenu component to your pages. Here is an example of how to create a simple panel menu:

<rich:panelMenu>
    <rich:panelMenuGroup label="Home">
        <rich:panelMenuItem label="Dashboard" />
        <rich:panelMenuItem label="Profile" />
    </rich:panelMenuGroup>
    <rich:panelMenuGroup label="Products">
        <rich:panelMenuItem label="Phones" />
        <rich:panelMenuItem label="Laptops" />
        <rich:panelMenuItem label="Tablets" />
    </rich:panelMenuGroup>
    <rich:panelMenuGroup label="Settings">
        <rich:panelMenuItem label="Account" />
        <rich:panelMenuItem label="Notifications" />
        <rich:panelMenuItem label="Privacy" />
    </rich:panelMenuGroup>
</rich:panelMenu>

This will create a simple panel menu with three groups: Home, Products, and Settings. Each group contains several menu items.

Customization

The Rich: PanelMenu component can be easily customized to match the look and feel of your web application. You can use CSS to style the menu items and groups, and you can also use custom icons and labels.

Here is an example of how to customize the panel menu with different skins and themes:

<rich:panelMenu skin="blueSky" mode="ajax">
    <rich:panelMenuGroup label="#{msg.home}">
        <rich:panelMenuItem label="#{msg.dashboard}">
            <f:param name="menu" value="home" />
            <f:param name="subMenu" value="dashboard" />
        </rich:panelMenuItem>
        <rich:panelMenuItem label="#{msg.profile}">
            <f:param name="menu" value="home" />
            <f:param name="subMenu" value="profile" />
        </rich:panelMenuItem>
    </rich:panelMenuGroup>
    <rich:panelMenuGroup label="#{msg.products}">
        <rich:panelMenuItem label="#{msg.phones}">
            <f:param name="menu" value="products" />
            <f:param name="subMenu" value="phones" />
        </rich:panelMenuItem>
        <rich:panelMenuItem label="#{msg.laptops}">
            <f:param name="menu" value="products" />
            <f:param name="subMenu" value="laptops" />
        </rich:panelMenuItem>
        <rich:panelMenuItem label="#{msg.tablets}">
            <f:param name="menu" value="products" />
            <f:param name="subMenu" value="tablets" />
        </rich:panelMenuItem>
    </rich:panelMenuGroup>
    <rich:panelMenuGroup label="#{msg.settings}">
        <rich:panelMenuItem label="#{msg.account}">
            <f:param name="menu" value="settings" />
            <f:param name="subMenu" value="account" />
        </rich:panelMenuItem>
        <rich:panelMenuItem label="#{msg.notifications}">
            <f:param name="menu" value="settings" />
            <f:param name="subMenu" value="notifications" />
        </rich:panelMenuItem>
        <rich:panelMenuItem label="#{msg.privacy}">
            <f:param name="menu" value="settings" />
            <f:param name="subMenu" value="privacy" />
        </rich:panelMenuItem>
    </rich:panelMenuGroup>
</rich:panelMenu>

This will create a panel menu with a blueSky skin and AJAX mode enabled. The menu items and groups are defined using message keys, which can be easily translated and customized for different languages and regions.
