Hello!
Found some issue. For Menu class there is no onSelectMenu function. This is not suitible to handle common MenuSelectedEvent and keep gamemode flow somewhere. Instad of this I created a class with static methods:

PHP код:

package ru.samp_net;
import java.util.ArrayList;
import java.util.List;
import net.gtaun.shoebill.event.menu.MenuSelectedEvent;
import net.gtaun.shoebill.object.Menu;
import net.gtaun.util.event.EventManager;
import net.gtaun.util.event.EventManagerNode;
/**

public class MenuController {
    @FunctionalInterface
    public static interface SelectMenuEvent {
        public void onSelect(MenuSelectedEvent event);
    }
    private static EventManagerNode eventManagerNode;
    private static List<Menu> menuList;
    private static List<SelectMenuEvent> eventList;
    
    public static void init(EventManager rootEventManager) {
        eventManagerNode = rootEventManager.createChildNode();
        menuList = new ArrayList<>();
        eventList = new ArrayList<>();
        setupEventHandlers();
    }
    public static void createMenuHandler(Menu menu, SelectMenuEvent event) {
        menuList.add(menu);
        eventList.add(event);
    }
    private static void setupEventHandlers() {
        eventManagerNode.registerHandler(MenuSelectedEvent.class, (event) -> onSelectMenu(event));
    }
    public static void destroy() {
        menuList.clear();
    }
    private static synchronized void onSelectMenu(MenuSelectedEvent event) {
        SelectMenuEvent menuEvent;
        for (int i = 0; i < menuList.size(); i++) {
            if (event.getMenu().getId() == menuList.get(i).getId()) {
                menuEvent = eventList.get(i);
                menuEvent.onSelect(event);
                menuList.remove(i);
                eventList.remove(i);
                return;
            }
        }
        
    }
} 


How to use:

In main gamemode class:

PHP код:

    protected void onEnable() throws Throwable {
        EventManager eventManager = getEventManager();
        //...
        MenuController.init(eventManager);
        //...
    } 


In somewhere where you need to create a menu (for example "skin shop"):

PHP код:

    private void drawMenu(RolePlayer rolePlayer) {
        Menu menu = SampObjectManager.get().createMenu("Choose skin", 1, 50.0f, 160.0f, 110.0f, 0.0f);
        menu.setColumnHeader(0, "Choose skin");
        menu.addItem(0, ">> Next");
        menu.addItem(0, "<< Previous");
        menu.addItem(0, "Done");
        menu.show(rolePlayer.getPlayer());
        MenuController.createMenuHandler(menu, (event) -> {
            switch (event.getRow()) {
                case 1:
                    // Show next skin
                    drawMenu(rolePlayer);
                    break;
                case 2:
                    // Show previous skin
                    drawMenu(rolePlayer);
                    break;
                default:
                    // Save changes
                    break;
            }
        });
    } 


UPD: Dev team! Please validate my code, i think that synchronized can help the onSelectMenu for concurrent removing elements from arraylist
