Setting up Mantine with app router

[surreal ice]

Hello I am new to Mantine and am setting up a test project with nextjs app router. I have the demo page rendering successfully and can toggle between dark and light mode.

When I try to add a Navigation bar (by copying the code samples from https://ui.mantine.dev/category/navbars/) I get a crude render - like some CSS is missing. See the attached screenshot.

Should I be expecting a render more like the samples at ui.mantine.dev or is this the expected behaviour? If not the expected behaviour can anyone suggest what the missing styles are?

Thanks!

Did you follow the app router setup on Mantine getting started?

Thanks David - yes I did and I am successfully rendering the root of the app, with the Mantine demo page displaying (using https://github.com/mantinedev/next-app-template)
