At the moment, PhpStorm doesn’t fully support Livewire 4 the same way it did previous versions. There isn’t a specific setting you’re missing — it’s mainly an IDE support gap.

JetBrains will likely add better support in upcoming PhpStorm updates once Livewire 4 stabilizes and its internals are fully documented. For now, keeping PhpStorm updated and using Laravel/Livewire-related plugins is your best option, but some features like autocomplete and component detection may be limited until official support lands.
