> If you'd rather write any necessary JS yourself or want to integrate with a framework other than React or Vue, we also provide every Tailwind UI component example as vanilla HTML that you can adapt yourself.
The js they use is mainly just showing how to hook headlessui up. Tailwind ui was never about buying fully fleshed ready to go react/etc components. They were building blocks you adapt. Guess a lot of people missed that and assume it’s copy paste. Catalyst will become that hopefully.
