Help choosing a documentation theme - fan of gitlab docs

Hi,

I’ve done a prototype doc site that makes me think Hugo is a good fit for us. But I’m struggling to find a good doc-focused theme I’m happy with. I’ve spent hours looking and hope it’s ok to ask here for suggestions.

I am a big fan of gitlab’s docs. But I want left nav menus that go down at least 4 menus. Clean structure, like Gitlab or Cordova.

Any suggestions? I don’t mind paying for a theme. I found plenty of examples, but none using Hugo.

Thanks!

Btw the hugo doc site itself is an option. But I’d prefer not to battle the menu, and preferably to have something a little more full featured out of the box. Such as support for exposing all content via index.json like the Hugo Learn Theme. Which works, but isn’t very visually appealing IMO.

I like hugo-book, the fixed TOC(right) and navigation(left) is pretty neat.
