Override default settings in NvChad Nvim - neovim

Question

I wish to change the layout_strategy for the telescope plugin from the NvChad default value of horizontal to vertical. This should be possible by setting layout_strategy = "vertical" somewhere...
According to the NvChad docs I can override the default settings specified in plugins/configs/telescope.lua in my own custom/init.lua, but I also found that it could/should be done in the custom/chadrc.lua.
Question
What line(s) do I have to add to what file to change the default layout_strategy for the telescope plugin, and only that (keeping other defaults intact)?
I have tried adding to
custom/chadrc.lua
M.telescope = {
layout_strategy = "vertical"
}
Also tried
M.telescope = {
defaults = {
layout_strategy = "vertical",
},
}
}
and
local o = vim.telescope.defaults
o.layout_strategy = "vertical"
But that does not seem to work.

In your chadrc.lua you would override options like so:
M.plugins = {
-- ...
["nvim-telescope/telescope.nvim"] = {
override_options = function()
return {
defaults = {
layout_strategy = "vertical",
layout_config = {
height = 0.95,
prompt_position = "top",
vertical = {
mirror = true,
preview_cutoff = 0,
},
},
},
}
end,
},
-- ...
}
I included my additional layout_config in case you want to have the preview part in the bottom half. Also preview_cutoff was necessary for me or the preview would never show up.
Essentially, the returned table of override_options will forcefully extend the default configs provided by NvChad and the result table would be passed into the setup function of the plugin.
Defining override_options is the way to go for pre-installed plugins of NvChad. If you deal with a new custom plugin, you'd rather need to call the setup function of the plugin on your own in the config function of the plugin declaration like so:
M.plugins = {
-- ...
["any-vendor/any-custom-plugin.nvim"] = {
config = function()
require('custom-plugin').setup({
-- ...
})
end,
},
-- ...
}
This is not relevant for telescope.nvim, since it is pre-installed, but I wanted to address this for completeness anyways.
