NameValue
component-typeorg.richfaces.PanelBarItem

tag-classorg.richfaces.taglib.PanelBarItemTag

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

Example:


...
    <rich:panelBar>
        <rich:panelBarItem label="Canon">
            ...
        </rich:panelBarItem>
        <rich:panelBarItem label="Nikon">
            ...
        </rich:panelBarItem>
    </rich:panelBar>
...

Example:

import org.richfaces.component.html.HtmlPanelBarItem;

...
HtmlPanelBarItem myBarItem = new HtmlPanelBarItem();
...

The "label" attribute defines text to be represented. If you can use the "label" facet, you can even not use the "label" attribute.

Example:


...
    <rich:panelBarItem...>
        <f:facet name="label">  
            <h:graphicImage value="/images/img1.png"/>
        </f:facet>
        ...
        <!--Any Content inside-->
        ...
    </rich:panelBarItem>
...

As it was mentioned above, panelBarItem is used for grouping any content inside within one panelBar, thus its customization deals only with specification of sizes and styles for rendering.

panelBar could contain any number of child panelBarItem components inside, which content is uploaded onto the client and headers are controls to open the corresponding child element.

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:panelBarItem> components at once:



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




In order to redefine styles for all <rich:panelBarItem> 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-panelbar-content{
        
background-color: #ecf4fe;
}
...

This is a result:


In the example a content background color was changed.

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

Example:


...
.myClass{
  
font-family: monospace;
}
...

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

Example:


<rich:panelBarItem ... headerClass="myClass"/>

This is a result:


As it could be seen on the picture above, the font family for header of active item was changed.
