How to cycle through autocompletion options?

[CCLDArjun]

I have this config:

require'cmp'.setup {
  sources = {
    { name = 'nvim_lsp' }
  }
}

local custom_attach = function(client, bufnr)
 -- this code gets executed when a language server is attached to a buffer
 -- you can add your keybindings and commands here.
end

-- The nvim-cmp almost supports LSP's capabilities so You should advertise it to LSP servers..
local capabilities = vim.lsp.protocol.make_client_capabilities()
capabilities = require('cmp_nvim_lsp').update_capabilities(capabilities)

local capabilities = require('cmp_nvim_lsp').update_capabilities(
  vim.lsp.protocol.make_client_capabilities()
)


vim.cmd [[packadd packer.nvim]]
require('packer').startup(function(use)
	use 'wbthomason/packer.nvim'
	use 'neovim/nvim-lspconfig'
end)

require'lspconfig'.pyright.setup {
  on_attach = custom_attach,
  capabilities = capabilities
}

require'lspconfig'.pyright.setup {
  on_attach = custom_attach,
  capabilities = capabilities
}
require'lspconfig'.rust_analyzer.setup {
  on_attach = custom_attach,
  capabilities = capabilities
}

it's using lspconfig. I can see the lsp autocompletion options but I'm not able to cycle through or select them. Hitting tab inserts a space character and ctrl-n or ctrl-p opens the vim autocomplete.

Hey mate, if you follow the example mappings that are provided in the nvim-cmp wiki, you should be able to find the key mappings that you need! Here's a link:

Keep in mind that the keybindings are specific to the snippet engine that you're using.
