    <title>Details of Usage</title>
    <para>The <emphasis role="bold">
        <property>&lt;rich:dataList&gt;</property>
      </emphasis> component allows to generate a list from a model.</para>
    <para>The component has the <emphasis>
        <property>&quot;type&quot;</property>
      </emphasis> attribute, which corresponds to the <emphasis>
        <property>&quot;type&quot;</property>
      </emphasis> parameter for the <emphasis>
        <property>&quot;UL&quot;</property>
      </emphasis> HTML element and defines a marker type. Possible values for <emphasis>
        <property>&quot;type&quot;</property>
      </emphasis> attribute are: <property>&quot;disc&quot;</property>,
        <property>&quot;circle&quot;</property>,
      <property>&quot;square&quot;</property>.</para>
    <para>Here is an example:</para>

    <programlisting role="XML"><![CDATA[...
    <h:form>
        <rich:dataList var="car" value="#{dataTableScrollerBean.allCars}" rows="5" type="disc" title="Car Store">
            <h:outputText value="#{car.make} #{car.model}"/><br/>
            <h:outputText value="Price:" styleClass="label"></h:outputText>
            <h:outputText value="#{car.price} "/><br/>
            <h:outputText value="Mileage:" styleClass="label"></h:outputText>
            <h:outputText value="#{car.mileage} "/><br/>
        </rich:dataList>

    <para>In the example the <emphasis>
        <property>&quot;rows&quot;</property>
      </emphasis> attribute limits number of output elements of the list.</para>

    <para><emphasis>
        <property>&quot;first&quot;</property>
    </emphasis> attribute defines first element for output. <emphasis>

    <para>The component was created basing on the <emphasis role="bold">
        <property>&lt;a4j:repeat&gt;</property>
      </emphasis> component and as a result it could be partially updated with Ajax. <emphasis>
        <property>&quot;ajaxKeys&quot;</property>
      </emphasis> attribute allows to define row keys that are updated after an Ajax request.</para>
    <para>Here is an example:</para>

    <para>
      <emphasis role="bold">Example:</emphasis>
    </para>
    <programlisting role="XML"><![CDATA[...
    <rich:dataList value="#{dataTableScrollerBean.allCars}" var="car" ajaxKeys="#{listBean.list}"

        ...
    </rich:dataList>
...
    <a4j:commandButton action="#{listBean.action}" reRender="list" value="Submit"/>
...
]]></programlisting>

    <para> In the example <emphasis>
        <property>&quot;reRender&quot;</property>
      </emphasis> attribute contains value of <emphasis>
        <property>&quot;id&quot;</property>
      </emphasis> attribute for <emphasis role="bold">
        <property>&lt;rich:dataList&gt;</property>
      </emphasis> component. As a result the component is updated after an Ajax request.</para>

    <title>Look-and-Feel Customization</title>

    <para>For skinnability implementation, the components use a <emphasis>

      </emphasis> Default style classes are mapped on <emphasis>
        <property>skin parameters.</property>
      </emphasis></para>

    <para>There are two ways to redefine the appearance of all <emphasis role="bold">

    <para>In order to redefine styles for all <emphasis role="bold">
      <property>&lt;rich:dataList&gt;</property>
    </emphasis> components on a page using CSS, it&apos;s enough to create classes with the
      same names (possible classes could be found in the tables <link linkend="dataLC"> above</link>) and define necessary properties in them. </para>
    
    <para>
      <emphasis role="bold">Example:</emphasis>

    <para>In the example the font style for list item text was changed.</para>
    
    <para>Also it’s possible to change styles of particular <emphasis role="bold"
      ><property>&lt;rich:dataLIst&gt;</property></emphasis> component. In this case you should create own style classes and use them in corresponding <emphasis role="bold"
        ><property>&lt;rich:dataList&gt;</property></emphasis> <emphasis><property>styleClass</property></emphasis> attributes. An example is placed below:</para>

    <para>The <emphasis><property>&quot;styleClass&quot;</property></emphasis> attribute for <emphasis role="bold"
