I would not suggest that, as Material-UI and TailwindCSS are CSS frameworks, and using them together might be conflicting. Try to stick to one framework if possible. You can find some of the ready-to-use components here https://headlessui.com, it is maintained by the same team who made TailwindCSS and you can style those components with TailwindCSS. I hope this helps you.

yes you can do it but I don't see the point using them both. I would strongly recommend you to stick to one of them instead.
