ZK Dynamic Menu Part 5 ~ Requirement Constraints

In Part 3, we have seen how to create left navigation menu using ZK Group Box and ZK Tool bar button dynamically and also in part 4, Using the same data set, We created two level menu in the top using Tab box and Tool bar as like this ZK Demo.

Now we will combine Part 3 and Part 4, i.e we will create 4 level menu, 1st level in Tabbox , 2nd Second Tab Panel Tool Bar Button, 3nd Level Left Group Box and 4th Level Tool Bar Button under each group Box.

MenuItem.java

package com.example.menu;

import java.util.ArrayList;
import java.util.List;

public class MenuItem {
	private String name;
	private List<MenuItem> children;
	private int level;

	public MenuItem(String name,int level) {
		this.name = name;
		this.level = level;
		children = new ArrayList<MenuItem>();
	}
	
	public void addChild(MenuItem node) {
		children.add(node);
	}

	public void appendChild(MenuItem child) {
		if (children == null)
			children = new ArrayList<MenuItem>();
		children.add(child);
	}
	
	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public List<MenuItem> getChildren() {
		return children;
	}

	public void setChildren(List<MenuItem> children) {
		this.children = children;
	}

	public int getLevel() {
		return level;
	}

	public void setLevel(int level) {
		this.level = level;
	}

}
