    </para>
    <programlisting role="XML"><![CDATA[...

    <title>Details of Usage</title>

    <para>All attributes are not required.</para>
    <para>Use <emphasis>
        <property>&quot;event&quot;</property>
      </emphasis> attribute to define an event for appearance of collapsing/expanding sublevels.
      Default value is <emphasis>
        <property>&quot;onclick&quot;</property>
      </emphasis>. An example could be seen below.</para>

    <para>
      <emphasis role="bold">Example:</emphasis>
    </para>
    <programlisting role="XML"><![CDATA[...
      <rich:panelMenu event="onmouseover">
            <!--Nested panelMenu components-->
      </rich:panelMenu>
...]]></programlisting>

    <para>Switching mode could be chosen with the <emphasis>
        <property>&quot;mode&quot;</property>
      </emphasis> attribute for all panelMenu items except ones where this attribute was redefined.
      By default all items send traditional request. </para>
    <para>The <emphasis>
        <property>&quot;expandMode&quot;</property>
      </emphasis> attribute defines the submission modes for all collapsing/expanding panelMenu
      groups except ones where this attribute was redefined. </para>
    <para>The <emphasis>
        <property>&quot;mode&quot;</property>
      </emphasis> and <emphasis>
        <property>&quot;expandMode&quot;</property>
      </emphasis> attributes could be used with three possible parameters.</para>

    <itemizedlist>
      <listitem>
        <para>Server (default)</para>
      </listitem>
    </itemizedlist>

    <para>The common submission of the form is performed and a page is completely refreshed.</para>

    <itemizedlist>
      <listitem>
        <para>Ajax</para>
      </listitem>
    </itemizedlist>

    <para>An Ajax form submission is performed, and additionally specified elements in the <emphasis>
        <property>&quot;reRender&quot;</property>
      </emphasis> attribute are reRendered.</para>

        <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 to items. Groups expand on the client side.</para>

    <para>
      <emphasis role="bold">Example:</emphasis>
    </para>
    <programlisting role="XML"><![CDATA[...
      <rich:panelMenu event="onclick" submitMode="none">

    <note><title>Note:</title> As the <emphasis role="bold">
        <property>&lt;rich:panelMenu&gt;</property>
      </emphasis> component doesn&apos;t provide its own form, use it between
      &lt;h:form&gt; and &lt;/h:form&gt; tags.</note>

    <para>The <emphasis>
        <property>&quot;expandSingle&quot;</property>
      </emphasis> attribute is defined for expanding more than one submenu on the same level. The
      default value is <emphasis>
        <property>&quot;false&quot;</property>
      </emphasis>. If it&apos;s true the previously opened group on the top level closes before
      opening another one. See the picture below.</para>
