Table 6.364. rich : panelMenuItem attributes

Attribute Name | Description
--- | ---
action | MethodBinding pointing at the application action to be invoked, if this UIComponent is activated by you, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the immediate property
actionListener | MethodBinding pointing at method accepting an ActionEvent with return type void
ajaxSingle | boolean attribute which provides possibility to limit JSF tree processing(decoding, conversion/validation, value applying) to the component which send the request only

Table 6.365. Component identification parameters

Name | Value
--- | ---
component-type | org.richfaces.PanelMenuItem
component-class | org.richfaces.component.html.HtmlPanelMenuItem
component-family | org.richfaces.PanelMenuItem
renderer-type | org.richfaces.PanelMenuItemRenderer
tag-class | org.richfaces.taglib.PanelMenuItemTag

### 6.71.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

          <rich:panelMenu>

                 ...

                <rich:panelMenuItem value="Item1"/>

                ...

          </rich:panelMenu>

    ...

### 6.71.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlPanelMenuItem;

    ...

    HtmlPanelMenuItem myPanelMenuItem = new HtmlPanelMenuItem();

    ...

### 6.71.5. Details of Usage

All attributes except "label" are optional. The "label" attribute defines text to be represented.

The "mode" attribute could be used with three possible parameters:

- `Server` (default)

Regular form submission request is used.

- `Ajax`

Ajax submission is used for switching.

- `None`

"Action" and "actionListener" attributes are ignored. Items don't fire any submits itself. Behavior is fully defined by the components nested into items.

Here is an example for value "none":

Example:

    ...

          <rich:panelMenu>

                ...

                <rich:panelMenuItem submitMode="none" onclick="document.location.href='http://labs.jboss.com/jbossrichfaces/">

                      <h:outputLink value="http://labs.jboss.com/jbossrichfaces/">

                            <h:outputText value="RichFaces Home Page"></h:outputText>

                      </h:outputLink>

                </rich:panelMenuItem>

                ...

          </rich:panelMenu>

    ...

There are two icon-related attributes. The "icon" attribute defines an icon. The "iconDisabled" attribute defines an icon for a disabled item.

Default icons are shown on the picture below:

Figure 6.211. Default icons

Here is an example:

Example:

    ...

          <rich:panelMenu>

                ...

                <rich:panelMenuItem ="Item 1.1" icon="chevronUp" />

                ...

          </rich:panelMenu>

    ...

As the result the picture is shown below:

Figure 6.212. Using an "icon" attribute

It's also possible to define a path to the icon. Simple code is placed below.

    ...

          <rich:panelMenu>

                ...

                <rich:panelMenuItem ="Item 1.1" icon="\images\img1.png" />

                ...

          </rich:panelMenu>

    ...

Information about the "process" attribute usage you can find here.

### 6.71.6. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:panelMenuItem> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:panelMenuItem> component

### 6.71.7. Skin Parameters Redefinition

Table 6.366. Skin parameters redefinition for a table element of the first level item

Skin parameters | CSS properties
--- | ---
generalFamilyFont | font-family
generalWeightFont | font-weight
generalSizeFont | font-size
generalTextColor | color
panelBorderColor | border-top-color

Table 6.367. Skin parameter redefinition for a disabled item

Parameter for disabled item | CSS properties
--- | ---
tabDisabledTextColor | color

### 6.71.8. Definition of Custom Style Classes

On the screenshot there are classes names that define styles for component elements.

Figure 6.213. Classes names

Figure 6.214. Classes names

Table 6.368. Classes names that define the first level items

Class name | Description
--- | ---
rich-pmenu-top-item | Defines styles for a top panel menu item
rich-pmenu-top-item-icon | Defines styles for a top panel menu item icon
rich-pmenu-top-item-label | Defines styles for a top panel menu item label

Table 6.369. Classes names that define the second and lower level items

Class name | Description
--- | ---
rich-pmenu-item | Defines styles for a panel menu item
rich-pmenu-item-icon | Defines styles for a panel menu item icon
rich-pmenu-item-label | Defines styles for a panel menu item label

Table 6.370. Classes names that define items state

Class name | Description
--- | ---
rich-pmenu-item-selected | Defines styles for a panel menu selected item
rich-pmenu-disabled-element | Defines styles for a disabled panel menu item
rich-pmenu-hovered-element | Defines styles for a hovered panel menu item

In order to redefine styles for all <rich:panelMenuItem> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-pmenu-hovered-element {

      background-color: #ff7800;

    }

    ...

This is a result:

Figure 6.215. Redefinition styles with predefined classes

In the example a hovered element background color was changed.

Also it's possible to change styles of particular <rich:panelMenuItem> component. In this case you should create own style classes and use them in corresponding <rich:panelMenuItem> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass {

            color: #a0a0a0;

    }

    ...

The "disabledClass" attribute for <rich:panelMenuItem> is defined as it's shown in the example below:

Example:

    <rich:panelMenuItem ... disabledClass="myClass"/>

This is a result:

Figure 6.216. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the text color for disabled item was changed.
