I can't see dirs sidebar inside of an article.

[David7ce]

Here's an example.

.
├── ciencia
│   ├── cientificos.md
│   ├── _index.md
│   ├── listado-experimentos.md
│   └── nota-ciencia.md
├── conceptos
│   ├── _index.md
│   ├── toroide.md
│   └── vacio.md

When I click on _index I see the left sidebar with directories and files. But inside the files the left sidebar disappears.

This is the yaml of an "ciencia/_index.md":

---
title: Ciencia
weight: 2
sidebar:
  open: true
---

This is the yaml of "ciencia/cientificos.md":

---
title: Científicos
---

See previous discussion: #18

To enable the documentation layout with a sidebar, you'll need to specify type: docs in the frontmatter of your Markdown file. This is necessary because your page resides outside the standard docs/ directory.
The default layout for single pages (such as the About page) doesn't include a sidebar, which is why you're not seeing it on your page.

Thanks for your quick response, I will try it.
