Nested API Navigation

[Foxtrek64]

My docfx site provides API documentation for two very large solutions containing between 10 and 20 projects each. While DocFx handles this very well, I end up with a very large generated toc, one for each separate namespace.

For instance, Tafs.Activities.Extensions.Models and Tafs.Activities.Extensions.Conditions each get their own entry, and expanding each displays the types held within.

Is there a way that I can increase the level of nesting? Preferably, I'd like to group by namespace level, like so:

Current:
- Tafs.Activities.Extensions.Models
- Tafs.Activities.Extensions.Conditions

Preferred:
- Tafs.Activities
  - Tafs.Activities.Extensions
    - Tafs.Activities.Extensions.Models
    - Tafs.Activities.Extensions.Conditions

I found the namespaceLayout metadata property which did what I wanted.
