Navigation Zoom
A navigation node can be set as a navigation zoom, meaning that when a user clicks on the node, the portal navigation is redisplayed with the children of the selected node as the top-level nodes. More information: Configuring Navigation Zoom.
When creating your own navigation iViews, you can implement the navigation zoom feature for each node specified as a navigation zoom.

1. Check if the navigation node is a navigation zoom, in one of the following ways:
¡ Use the ifNavNodeIsNavZoom tag of the navigation tag library.
¡ Check the navigation zoom attribute of the navigation node, as follows:
node.getAttributeValue("com.sap.portal.navigation.PortalPlace")
2. Create a link to the navigation zoom component and specify the current navigation node.
<a
href="/irj/servlet/prt/portal/prtroot/com.sap.portal.navigation
.helperservice.PortalPlaceRedirect?ppLaunchURL=myNodeID">
where myNodeID is the navigation node ID.
