how to use shadcn only for a portion of my nextjs app ?

[BadisKefi]

i tried to install shadcn using the cli then moving the shadcn code outside the globals.css to shadcn.css and after that created a component that i called ShadcnWrapper.tsx , i wanted to use this to wrap the portions of my appp that needs shadcn like a simple form i made using shadcn but the issue is that it forces the full app to follow shadcn somehow , like theme , colors ...
