Is there anyway to flat nav level

[NamekMaster]

Enable tabs make mkdocs render pages from second level. Is is possible if I want it render from third level ?
For example,

nav:
  - group1:
     - folder:
        - page1: page1.md
  - group2:
     - folder:
        - page1: page1.md

I'd like to override default tabs with multiple level dropdown, and I need mkdocs render start from page1 level.
Totally two things:

1. The tabs become from group1, group2 to group1->folder, group2->folder, that could implement by overriding tabs block.
2. The content of page1 rendered without the folder section, I didn't find anyway to do this.

We only support tabs from the first level. If you want it from the second, as you already noticed, you'd need to override the specific partials. Other than that, you might also split your project into multiple MkDocs projects and build them separately.
