Submenu into another submenu

Hello, I am using Native UI to create a menu. I have Player Options and Vehicle Options. I want to put some cars in a submenu in Vehicle Options.
Kind regards,

I think this is an answer. Here you go! Custom/ Add-on Vehicle Spawner Menu (NativeUI Lua)

Thank you for answering. Im gonna try use a code like this.
