Could a modalPanel be used for a a4j-include navigation similar to http://livedemo.exadel.com/a4j-include/.

If o, I am not sure how go about this. any advise?

<rich:modalPanel id="contact-modal-container"
 minHeight="200" minWidth="450" height="200" width="500" zindex="20000">
 <f:facet name="header">
 <h:outputText value="Contact Us" />
 </f:facet>
 <f:facet name="controls">
 <h:graphicImage value="/images/universal_image/close.png"
 style="cursor:pointer" onclick="Richfaces.hideModalPanel('contact-modal-container')" />
 </f:facet>
 <ui:decorate template="/pages/common/universal/contact.xhtml" />


 </rich:modalPanel>
