I've been configuring my Neovim for quite a while now. This command menu seems a little ugly with the transparent background. I'd be great if I could add a border for this menu. How can I do that ?

enter image description here

I'll accept both lua and vim-lang answers.

  • You cannot add a border but you can make it opaque: :set pumblend =0. In Vim, it shouldn't be transparent as there is no option to make it transparent, so you should remove the mention of vim from your question title.

  • I previously tried something like vim.cmd[[:highlight Pmenu guibg=NONE cterm=NONE term=NONE]] to make my cmp completion menus transparent. Can I have different highlights for the cmp completion menu and this completion menu ?

  • No. Both those menus use the same highlight group.

I would propose you to use the wilder plugin

With the following settings:

call wilder#set_option('renderer', wilder#popupmenu_renderer(wilder#popupmenu_border_theme({
      \ 'highlights': {
      \   'border': 'Normal',
      \ },
      \ 'border': 'single',
      \ })))


Here's the Lua implementation of what @Vivian De Smedt mentioned.

local status_ok, wilder = pcall(require, "wilder")
if not status_ok then
  print("wilder plugin not found")

wilder.set_option('renderer', wilder.popupmenu_renderer(
    highlights = { border = 'Normal' },
    border = 'single',

wilder.setup({modes = {':', '/', '?'}}) 

Another way:

If you use nvim-cmp for auto-completion like me, you can apply cmp popup menu borders to the command-line using cmp-cmdline plugin. This plugin will also let you fuzzy find the options.

local cmp_status_ok, cmp = pcall(require, "cmp")
if not cmp_status_ok then


  -- .... (other setups)

  -- Add borders around the popup window
  window = {
    completion = cmp.config.window.bordered(),  


-- Enable command-line completion 
cmp.setup.cmdline(':', {
  sources = {
    { name = 'cmdline' },
  formatting = {
    fields = { "abbr" },
