LUA item gossip help

[naturaunglosar]

I need some help with a LUA script
I want to make an item that can open me a vendor tab when I click on it.For example when i click on the item a new ,,window'' appears and when I choose ,,I want to buy food"-a vendor window will appear.
Can someone help me?
Sorry for bad english.

Heya, wait a moment i think there is a command in LuaHypArc for opening the vendor window...

anyway here is the structure of an item with gossip:

local LuaVendorItem = ITEMID


function LuaVendor_OnUse(item, event, player)
    LuaVendor_Menu(item, player)
end


function LuaVendor_Menu(item, player)                   
    item:GossipCreateMenu(1000, player, 0)
    item:GossipMenuAddItem(9, "I want to buy food.", 300, 0)
    item:GossipMenuAddItem(0, "Nevermind.", 301, 0)
    item:GossipSendMenu(player)
end

function LuaVendor_OnSelect(item, event, player, id, intid, code)
if (intid == 300) then
  --[[ Lua Command for VendorWindow here ]]--
end


if (intid == 301) then
    player:GossipComplete()
end

end
 
RegisterItemGossipEvent(LuaVendorItem, 1, "LuaVendor_OnUse")
RegisterItemGossipEvent(LuaVendorItem, 2, "LuaVendor_OnSelect")

You only need to add your item id in ITEMID.
