Is it possible to list a root level page or leaf-bundle in "Navigation"?

It is allowed to create leaf bundles directly under the "content" directory.

I tried following content structure.

content/
├── Section1
│   ├── _index.md
│   └── page.md
├── leaf_bundle
│   └── index.md
└── page1.md

The navigation only shows "Section1".

Is it possible to list a root level page or leaf-bundle in "Navigation"?

The content structure depends on the menu you want to use. Using the auto-generated file-tree menu only branch bundles are supported. If you want to use a mix of multiple types in your content structure, you would need to switch to the manual bundle menu.

Thanks.
But I prefer the "auto-generated" method!

Following customization works to some extent.
// Not checking for bad side effects etc.

Replacing Sections with Pages in hugo-geekdoc/layouts/partials/menu-filetree.html

{{ template "tree-nav" dict "sect" .Site.Home.Sections "current" $current }}
=>
{{ template "tree-nav" dict "sect" .Site.Home.Pages "current" $current }}

Sure, it's up to you to customize partials to your needs. The intention of the file tree menu is to work with branch bundles.
