Is there a way to import 3rd part kits or web components like these here; https://ui.shadcn.com/
Not yet directly, but with the marketplace coming I think there will be people that will convert popular kits including that one to weweb and then you may get it from there
Hey ! I just release a first version of 16 UI like Shadcn component if you like !
If you want more, let me know here ! I am still wondering if you would prefer dropzone or props component
