Visualizing data with tree
The tree component visualizes hierarchical data in the tree format.
How to do it…
The data for tree is provided as instances of org.primefaces.model.TreeNode, which correspond to the nodes in the tree. A pure client-side tree might be useful to create tree-based navigation menus. A basic data model for a tree could be constructed as follows:
TreeNode root = new DefaultTreeNode("Root", null); TreeNode node1 = new DefaultTreeNode("Node1", root); TreeNode node2 = new DefaultTreeNode("Node2", root); TreeNode node11 = new DefaultTreeNode("Node1.1", node1); TreeNode node12 = new DefaultTreeNode("Node1.2", node1); TreeNode node21 = new DefaultTreeNode("Node2.1", node2); TreeNode node211 = new DefaultTreeNode("Node2.1.1", node21); ...Get PrimeFaces Cookbook - Second Edition now with the O’Reilly learning platform.
