how to access liferay menu from portlet - gwt

Question

I define a menu in navigation.vm file which working good in liferay project.
But I want to access this menu from my portlet.
Is there any way to access menu from portlet entry point or view.jsp????

Answer 1

import liferay-ui taglib:
<%# taglib uri="http://liferay.com/tld/ui" prefix="liferay-ui" %>
then you can use
<liferay-ui:navigation displayStyle="from-level-0" >
</liferay-ui:navigation>
Note: setting displayStyle="from-level-0" to give you the normal behavior like on navigation.vm, you can play with attributes differently to get other behavior.

Answer 2

This link describes the way of getting menu items in a jsp directly.
The below code is reproduced directly from the above link with some improved formatting:
<%# taglib uri="http://liferay.com/tld/theme" prefix="liferay-theme" %>
<%# taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>
<%# page import="java.util.List" %>
<%# page import="java.util.ArrayList" %>
<%# page import="com.liferay.portal.model.Layout"%>
<%# page import="com.liferay.portal.kernel.util.WebKeys"%>
<%# page import="com.liferay.portal.theme.NavItem" %>
<%# page import="com.liferay.portal.theme.RequestVars" %>
<%# page import="com.liferay.portal.theme.ThemeDisplay"%>
<portlet:defineObjects />
<liferay-theme:defineObjects />
<div style="width:100%">
<%
//ThemeDisplay themeDisplay = (ThemeDisplay) request.getAttribute(WebKeys.THEME_DISPLAY);
String title = themeDisplay.getLayout().getName(themeDisplay.getLocale());
List<NavItem> navItems = new ArrayList<NavItem>();
if (layout != null) {
RequestVars requestVars = new RequestVars(request, themeDisplay, layout.getAncestorPlid(), layout.getAncestorLayoutId());
navItems = NavItem.fromLayouts(requestVars, layouts);
}
for (NavItem navItem : navItems) {
if (navItem.getName().equalsIgnoreCase(title)) {
if (navItem.hasChildren()) {
for(NavItem navChild : navItem.getChildren()) {
%>
<div style="float:left;" class="newsMenuPortlet">
<a href="<%= navChild.getURL() %>" <%=navChild.getTarget() %>>
<%= navChild.getName() %>
</a>
</div>
<%
} // inner for-loop ends here
}
}
}// outer for-loop ends here
%>
</div>
