All the popup created by nui.nvim uses unlisted scratch buffer, created by vim.api.nvim_create_buf(false, true).

If you want to set a specific filetype, you can pass buf_options = { filetype = 'anything' } to the popup_options table when creating the popup.

Also as a default Neovim behavior - for any popup buftype is nofile, and for input buftype is prompt.

Thank you, but where I can put it? For example, neo-tree use nui_ui for filter files. So I should to put it globally in nui. How to do it? Something like override input and menu in vim with nui?

So I should to put it globally in nui.

nui.nvim doesn't have any global option. This is just a library that other plugins use. If you want to configure something for neo-tree it's better to ask it on neo-tree repo.

Something like override input and menu in vim with nui?

For vim.ui.* overrides, you can just put it inside the popup_options table. I see in your recording that you have set win_options, you can put buf_options just like that. e.g.

local popup_options = {
  -- ... other options
  buf_options = {
    -- ... buf options
  },
  win_options = {
    -- ... win options
  },
}
