Nesting multiple navigation levels

[rmscode]

I know that this is valid:

- Home: index.md
- Parent:
    - 'Nested Page': 'somepage.md'
    - 'Nested Parent':
        - 'Nested page': `someotherpage.md`

But this is not?

- Home: index.md
- Parent:
    - 'Nested Page': 'somepage.md'
    - 'Nested Parent':
        - 'Nested page': `someotherpage.md`
        - 'Nested Child':
            - 'Nested Child Page': 'someotherpage2.md'

This is what I was trying to do, but received the error MkDocs encountered an error parsing the configuration file: mapping values are not allowed here:

- Hardware: 
    - hardware/index.md
    - Dell EMC: 
      - hardware/dell-emc/dell-emc.md
        - S4048-ON: # <-- Not allowed here
          - hardware/dell-emc/S4048-ON/overview.md
          - hardware/dell-emc/S4048-ON/os9.md
          - hardware/dell-emc/S4048-ON/os9-debugging.md
          - hardware/dell-emc/S4048-ON/os9-file-management.md
          - hardware/dell-emc/S4048-ON/os9-logging.md
          - hardware/dell-emc/S4048-ON/os9-tty-access.md
          - hardware/dell-emc/S4048-ON/os9-ufd.md
          - hardware/dell-emc/S4048-ON/os9-vlan.md
          - hardware/dell-emc/S4048-ON/os9-vlt.md
          - hardware/dell-emc/S4048-ON/os9-other.md
          - hardware/dell-emc/S4048-ON/os10.md

Is anyone aware of a way to achieve what I am looking for?

Hello @rmscode,
your third example shows a section nested in a page:

      - hardware/dell-emc/dell-emc.md
        - S4048-ON: # <-- Not allowed here

so this isn't allowed. Only sections can have subsections. Pages can't be sections at the same time.
mkdocs-material plugin uses a trick and allows to merge index pages into the section in the navigation, but this still wouldn't let you use the example provided: https://squidfunk.github.io/mkdocs-material/setup/setting-up-navigation/#section-index-pages

Remove a bit of the indentation from - S4048-ON: so it has the same indentation level as - hardware/dell-emc/dell-emc.md and adjust the rest of the entries.

To maybe simplify this with a short sentence. Only indent right after :, never after .md

That extra bit of indentation was definitely an error on my part 🤦‍♂️. Thanks for your reply.
