        size={
            width="60%",
            height="60%",
        }
    },
    Layout.Box({
        Layout.Box(input,{size="10%"}),
        Layout.Box(menu,{size="50%"})
    },{dir='col'})
)

layout:mount()

Menu should only be used when it's directly interactive. If you're only using it to display some lines, you should use Popup + NuiTree instead.

local popup = Popup({
  border = 'double',
})

local tree = Tree({
  bufnr = popup.bufnr,
  nodes = {
    Tree.Node({ text = "A" }),
    Tree.Node({ text = "B" }),
  },
})

tree:render()

Then for adding new item:

tree:add_node(Tree.Node({ text = "C" }))
tree:render()
