I think GP meant components that require JS like data tables which TailwindUI doesn't solve.

I guess something like Tailwind Headless (only available for React and Vue):

https://headlessui.dev/

I ported this library to Svelte recently: https://github.com/rgossiaux/svelte-headlessui

As a side note, Tailwind UI does include some components that require JS--that's what the Headless UI library is for. But it's also true that it's not a comprehensive component library; still missing things like a combobox or a date picker.
