使用NUI列出FiveM Vehicle Extra

我正在创建一个独立的车辆额外菜单。我遇到的问题是，如果我生成车辆A并且它有4个额外选项，它们可以正常工作。但是，如果我生成车辆B并且它有8个选项，菜单仍将仅显示来自先前车辆A的4个选项。这是真实的，无论我是否离开车辆A或删除它。有什么想法可以重置它以读取正确的车辆？

local AvailableExtras = {['VehicleExtras'] = {}}
local Items = {['Vehicle'] = {}}
local MenuExists, Vehicle
_menuPool = NativeUI.CreatePool()
mainMenu = NativeUI.CreateMenu("车辆额外", "~b~选择额外")
_menuPool:Add(mainMenu)
_menuPool:MouseControlsEnabled (false);
_menuPool:MouseEdgeEnabled (false);
_menuPool:ControlDisablingEnabled(false);

Citizen.CreateThread(function()
        while true do
                Citizen.Wait(0)
                _menuPool:MouseControlsEnabled (false);
                _menuPool:MouseEdgeEnabled (false);
                _menuPool:ControlDisablingEnabled(false)
                _menuPool:ProcessMenus()
                if IsControlJustPressed(1, 56) then
                    mainMenu:Visible(not mainMenu:Visible())
                end
        end
end)
