Class CmsJspNavBuilder

java.lang.Object

org.opencms.jsp.CmsJspNavBuilder

public class CmsJspNavBuilder
extends java.lang.Object

Bean to provide a convenient way to build navigation structures based on the CmsJspNavElement.

Use this together with the CmsJspActionElement to obtain navigation information based on the current users permissions. For example, use getNavigationForFolder(String) and pass the value of the current OpenCms user context uri obtained from CmsRequestContext.getUri() as argument to obtain a list of all items in the navigation of the current folder. Then use a simple scriptlet to iterate over these items and create a HTML navigation.

6.0.0
