## Creating the Component with a Page Tag

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>
    ...

## Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlPanelBar;
    ...
    HtmlPanelBar myBar = new HtmlPanelBar();
    ...

## Details of Usage

As it was mentioned above, panelBar is used for grouping any content on the client, thus its customization deals only with specification of sizes and styles for rendering.

"width" and "height" (both are 100% on default) attributes stand apart.

Style attributes are described further.

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.

## 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:panelBar> components at once:

- Redefine the corresponding skin parameters

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

## Skin Parameters Redefinition

Skin parameter redefinition for a whole component

Skin parameter | CSS properties
--- | ---
headerBackgroundColor | border-color

## Definition of Custom Style Classes

There is one predefined class for the <rich:panelBar> , which is applicable to a whole component, specifying padding, borders, and etc.

Style classes

Class name that define a component appearance

Class name | Class description
--- | ---
rich-panelbar | Defines styles for a wrapper <div> element of a component

Other classes responsible for elements rendering are described for child <rich:panelBarItem> elements and could be found in the components chapters.

Style component classes

A class attribute | A component element defined by an attribute
--- | ---
styleClass | Applicable to a whole component (together with headers)
headerClass | Applicable to a header element
contentClass | Applicable to a content

In order to redefine styles for all <rich:panelBar> 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{
            font-style: italic;
    }
    ...

This is a result:

Redefinition styles with predefined classes

In the example header and content font style was changed.

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

Example:

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

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

Example:

    <rich:panelBar ... contentClass="myClass"/>

This is a result:

Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font family for content were changed.
