    <title>Details of Usage</title>

    <para>All attributes except <emphasis>
        <property>&quot;label&quot;</property>
      </emphasis> are optional. The <emphasis>
        <property>&quot;label&quot;</property>
      </emphasis> attribute defines text to be represented.</para>
    <para>Switching mode could be chosen with the<emphasis>
        <property> &quot;expandMode&quot;</property>
      </emphasis> attribute for the concrete panelMenu group.</para>
    <para>The <emphasis>
        <property>&quot;expandMode&quot;</property>
      </emphasis> attribute could be used with three possible parameters:</para>

    <itemizedlist>

    <para><emphasis>
        <property>&quot;Action&quot;</property>
      </emphasis> and <emphasis>
        <property>&quot;actionListener&quot;</property>
      </emphasis> attributes are ignored. Items don&apos;t fire any submits itself. Behavior is
      fully defined by the components nested into items.</para>

    <para>There are three icon-related attributes. The <emphasis>
        <property>&quot;iconExpanded&quot;</property>
      </emphasis> attribute defines an icon for an expanded state. The <emphasis>
        <property>&quot;iconCollapsed&quot;</property>
      </emphasis> attribute defines an icon for a collapsed state. The <emphasis>
        <property>&quot;iconDisabled&quot;</property>
      </emphasis> attribute defines an icon for a disabled state.</para>

    <para>Default icons are shown on the picture below:</para>

            </rich:panelMenuGroup>
      </rich:panelMenu>
...]]></programlisting>
    <para> As the result the pictures are shown below. The first one represents the collapsed state,
      the second one - expanded state:</para>

      <title>Collapsed state</title>

      <mediaobject>

    <para>It&apos;s also possible to define a path to the icon. Simple code is placed below.</para>
