Page nav layout component
When you create an app in Plasmic, you get a default Page Layout component that is automatically added to all pages.
You can customize this by double clicking on it. It is meant to be a simple-to-customize component that comes out-of-the-box with responsive layout, intelligent dark/light theme detection, customizable loading states, and more. You can also optionally customize the loading state.
This is a normal Plasmic component, but has been set as the “default page wrapper” for the project. If you want, you can instead set a different component to be the default page wrapper. You can do this by going to the Components left sidebar tab, right-clicking a component, and setting it as the default page wrapper.
