Primary navigation is missing. Where did it go?

Contribution guidelines

• I’ve read the contribution guidelines and wholeheartedly agree

I’ve found a bug and checked that …

• … the problem doesn’t occur with the mkdocs or readthedocs themes
• … the problem persists when all overrides are removed, i.e. custom_dir, extra_javascript and extra_css
• … the documentation does not mention anything about my problem
• … there are no open or closed issues that are related to my problem

Description

Here’s a look at the most recent deploy preview of my site in Netlify.

As you can see, the navigation section (on the left) is completely gone. Here’s what the same exact code renders on my local machine.

What’s the difference?

The code is the same. The main difference is that,

• locally I use mkdocs-material @ commit 62d4e1caac3cca088cce4c16ed399fa25f958fe3 (older)
• my deploy preview uses mkdocs-material @ commit c70dcb54465092f7f527a04385c79597e990133e (newer)

So, clearly something in the newer version of Material is not compatible with my nav. See my mkdocs.yml below.

Expected behaviour

The navigation section should not be missing.

Actual behaviour

The navigation section is missing (as shown in the image).

Steps to reproduce

Create a nav similar to mine in mkdocs.yml and I suspect you will see the same behavior.

Package versions

I don’t have direct access to the Netlify machine, but from inspecting the deploy logs I see the following

• Python: 3.8
• MkDocs: https://****@github.com/squidfunk/mkdocs-material-insiders.git to commit c70dcb54465092f7f527a04385c79597e990133e
• Material: mkdocs-1.3.1

@squidfunk Hey yes, sorry for the hasty issue report. I’ll write up something more useful when I have time to narrow things down.

[squidfunk]

No worries! Sometimes upgrades to partials are necessary, but it’s hard to say when something will break and must be considered a breaking change. I’m sorry for the inconvenience and glad you could solve it so quickly.
