Is it possible to set buf highlight indside builtin select window

[fitrh]

I want to set highlight for code action source name but I don't know where to hook to modify the window and the item

At the moment there are very limited controls for customizing the UI, because I don't like the idea of supporting an API that diverges from the core vim.ui.input. However, if you want to do your own post-processing on the window you should be able to hook into the FileType autocmd.

function _G.add_highlights()
  ...
end
vim.cmd([[autocmd FileType DressingSelect lua add_highlights()]])

I see, thank you, I ended up creating after/ftplugin/DressingSelect.lua to do the thing
