Allow hiding of single articles via frontmatter

Description

While writing docs it often is necessary to completely hide references to articles temporarily (in-between publishing doc updates).

It is possible to fully customize what articles show up via the sidebar config file, but AFAIK it is not possible to hide single articles via the YAML frontmatter in such a manner:

---
sidebar_position: 1
title: some title
hidden: true
---

other option names could be:

• publish
• draft

In essence what this would do is not take the markdown file into account when generating the static HTML or when deploying the webapp.

Has this been requested on Canny?

Motivation

This helps in simplifying documentation management in general for larger projects. It often is the case that writers draft new documents but these new docs shouldn't show up online. This could be solved via separating the new work into its own branch but this is rather clumsy.

API design

sidebar_position: 1
title: some title
hidden: true

Have you tried building it?

Self-service

• I'd be willing to contribute this feature to Docusaurus myself.
