public class Node{

private String value;
private List<Node> children;
//getter setter

}

I have to display Node as combobox having value Yes and No. when Yes is selected children Node will display same will repeat until children is found empty.

This hierarchy is infinite like Node->children->children->....->children.

How can I display this parent child in ZK UI?
