I don't know about any full admin templates available, but you can watch Adam Wathan (Tailwind's creator) build these on his youtube channel which will hopefully provide you with what you need. Also, keep an eye on Tailwind UI, which will likely provide more of what you need. Finally, you might want to check out Awesome Tailwind.

check this github.com/tailwindcomponents/dash...

This one is free and great !

You should check out Tails.

Tails is a drag-and-drop TailwindCSS page builder and a beta version just got released a couple of days ago.
