When I developing a Laravel, Inertia, and Svelte, CSS classes from node_modules somehow are included at my PhpStorm autocomplete. It's kinda annoying since I don't need them.
Is there any ways to exclude this files from included to autocomplete?

I had the same problem with public/build and public/vendor folder.
If you exclude the folders, phpstorm will not index them and will not show them in autocomplete
There are 2 ways to exclude list;
1- You can exclude the files or folders you want by following the Settings > Directories path (Here wildcard properties such as *.css are also listed)
2- You can exclude with Mark Directory as option by hovering over the folder in the project tree
