Table 6.188. rich : menuItem 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
binding | The attribute takes a value-binding expression for a component property of a backing bean
bypassUpdates | If "true", after process validations phase it skips updates of model beans on a force render response. It can be used for validating components input
data | Serialized (on default with JSON) data passed on the client by a developer on AJAX request. It's accessible via "data.foo" syntax
disabled | If "true" sets state of the item to disabled state. Default value is "false".
eventsQueue | Name of requests queue to avoid send next request before complete other from same event. Can be used to reduce number of requests of frequently events (key press, mouse move etc.)
focus | id of element to set focus after request completed on client side
icon | Path to the icon to be displayed for the enabled item state
iconClass | Class to be applied to icon element
iconDisabled | Path to the icon to be displayed for the disabled item state.
iconStyle | CSS style rules to be applied to icon element
id | Every component may have a unique id that is automatically created if omitted
ignoreDupResponses | Attribute allows to ignore an Ajax Response produced by a request if the newest 'similar' request is in a queue already. ignoreDupResponses="true" does not cancel the request while it is processed on the server, but just allows to avoid unnecessary updates on the client side if the response isn't actual now
immediate | True means, that the default ActionListener should be executed immediately (i.e. during Apply Request Values phase of the request processing lifecycle), rather than waiting until the Invoke Application phase
labelClass | Class to be applied to label element
limitToList | If "true", updates on client side ONLY elements from this 'reRender' property. If "false" (default) updates all rendered by ajax region components
onbeforedomupdate | JavaScript code for call before DOM has been updated on client side
onclick | HTML: a script expression; a pointer button is clicked
oncomplete | JavaScript code for call after request completed on client side
onmousedown | HTML: script expression; a pointer button is pressed down
onmousemove | HTML: a script expression; a pointer is moved within
onmouseout | HTML: a script expression; a pointer is moved away
onmouseover | HTML: a script expression; a pointer is moved onto
onmouseup | HTML: script expression; a pointer button is released
onselect | HTML: script expression; The onselect event occurs when you select some menu item
process | Id['s] (in format of call UIComponent.findComponent()) of components, processed at the phases 2-5 in case of AjaxRequest caused by this component. Can be single id, comma-separated list of Id's, or EL Expression with array or Collection
rendered | If "false", this component is not rendered
requestDelay | Attribute defines the time (in ms.) that the request will be wait in the queue before it is ready to send. When the delay time is over, the request will be sent to the server or removed if the newest 'similar' request is in a queue already
reRender | Id['s] (in format of call UIComponent.findComponent()) of components, rendered in case of AjaxRequest caused by this component. Can be single id, comma-separated list of Id's, or EL Expression with array or Collection

Table 6.189. Component identification parameters

Name | Value
--- | ---
component-type | org.richfaces.MenuItem
component-class | org.richfaces.component.html.HtmlMenuItem
component-family | org.richfaces.DropDownMenu
renderer-type | org.richfaces.MenuItemRenderer
tag-class | org.richfaces.taglib.MenuItemTag

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

Here is a simple example as it could be used on a page:

Example:

    ...

        <rich:dropDownMenu>

            ...

            <rich:menuItem value="Active"/>

            ...

        <rich:dropDownMenu>

    ...

### 6.48.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlMenuItem;

    ...

    HtmlMenuItem myMenuItem = new HtmlMenuItem();

    ...

### 6.48.5. Details of Usage

The "value" attribute defines the text representation for an item element.

There are two icon-related attributes. The "icon" attribute defines an icon. The "iconDisabled" attribute defines an icon for a disabled item. Also you can use the "icon" and "iconDisabled" facets. If the facets are defined, the corresponding "icon" and "iconDisabled" attributes are ignored and the facets content is shown as an icon. It could be used for an item check box implementation.

Here is an example:

    ...

        <f:facet name="icon">

            <h:selectBooleanCheckbox value="#{bean.property}"/>

        </f:facet>

    ...

The <rich:menuItem> "submitMode" attribute can be set to three possible parameters:

- `Server` (default)

Regular form submission request is used.

- `Ajax`

Ajax submission is used for switching.

- `None`

The "action" and "actionListener" item's attributes are ignored. Menu items don' fire any submits themselves. The behavior is fully defined by the components nested into items.

For example, you can put any content into an item, but, in this case, you should set the "mode" attribute as "none" .

Here is an example:

    ...

        <rich:dropDownMenu>

            ...

            <rich:menuItem submitMode="none">

                <h:outputLink value="www.jboss.org"/>

            </rich:menuItem>

            ...

        <rich:dropDownMenu>

    ...

You can use the "disabled" attribute to set the item state.

Here is an example:

    ...

        <rich:dropDownMenu>

            <rich:menuItem value="Disable" disabled="true"/>

        <rich:dropDownMenu>

    ...

## Note:

The <rich:menuItem> component was designed to be used only for pop-up menu list creation.

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

### 6.48.6. 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:menuItem> components at once:

- Redefine the corresponding skin parameters

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

### 6.48.7. Skin Parameters Redefinition

Table 6.190. Skin parameters redefinition for an item

Skin parameters | CSS properties
--- | ---
generalFamilyFont | font-family
generalSizeFont | font-size

Table 6.191. Skin parameters redefinition for a hovered item

Skin parameters | CSS properties
--- | ---
tipBorderColor | border-color
tipBackgroundColor | background-color

generalTextColor | color

### 6.48.8. Definition of Custom Style Classes

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

Figure 6.108. Classes names

Table 6.194. Classes names that define an appearance of item elements

Class name | Description
--- | ---
rich-menu-item | Defines styles for a wrapper <div> element for an item
rich-menu-item-label | Defines styles for a label of an item
rich-menu-item-icon | Defines styles for the left icon of an item

Table 6.195. Classes names that define different states

Class name | Description
--- | ---
rich-menu-item-disabled | Defines styles for a wrapper <div> element of an item
rich-menu-item-enabled | Defines styles for a wrapper <div> element of an enabled item
rich-menu-item-hover | Defines styles for a wrapper <div> element of a hover item
rich-menu-item-label-disabled | Defines styles for a label of a disabled item
rich-menu-item-icon-disabled | Defines styles for the left icon of a disabled item
rich-menu-item-label-enabled | Defines styles for a label of an enabled item
rich-menu-item-icon-enabled | Defines styles for the left icon of an enabled item
rich-menu-item-label-selected | Defines styles for a label of a selected item
rich-menu-item-icon-selected | Defines styles for the left icon of a selected item

In order to redefine styles for all <rich:menuItem> 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-menu-item-disabled{

            font-style: italic;

    }

    ...

This is a result:

Figure 6.109. Redefinition styles with predefined classes

In the example a disabled item font style was changed.

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

Example:

    ...

    .myClass{

            border-color: #bed6f8;

            background-color: #ffffff;

    }

    ...

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

Example:

    <rich:menuItem ... selectStyle="myClass">

This is a result:

Figure 6.110. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the background color and border color for selected item were changed.
