Troubleshooting nested pages in Nuxt.js

Nested pages in Nuxt.js are structured as pages within pages, allowing for organized branching and sectioning of content. The implementation of these pages involves setting up directories and files within the pages directory of a Nuxt.js application, where the framework automatically configures routing based on file names. A root-level page must be established first, which can then contain nested pages, and further down, deeply-nested pages, following a clear directory structure. Challenges that developers face include issues with rendering, often due to missing <NuxtLink> or <NuxtChild> components, which are crucial for displaying nested content. Solutions involve ensuring correct directory structures and file placements, as well as properly utilizing these components to manage content visibility between parent and nested pages. The tutorial also highlights the importance of the index.vue file for homepage rendering and demonstrates how to troubleshoot common rendering issues with nested and deeply-nested pages.
