Selecting tags that have at least one tagged object

[kirgus]

I choose tags sequentially. How do I highlight tags that also have objects tagged to them?

The dumbest thing I can think of is to extract all tags from tagged objects.

Not a beautiful solution, but I'm sure there is a beautiful one

        $ids = Course::withAllTags($this->selected)->pluck('id');

        $tagIdList = Db::table('taggables')
            ->whereIn('taggable_id', $ids)
            ->distinct('tag_id')
            ->pluck('tag_id');

        dd(
            Tag::whereIn('id', $tagIdList)->pluck('name')->all()
        );
