Align navebar’s items on both left and right side

[EftePA]

Hi everyone,
I am using Hugo Blox and everything is working nicely. I just need to divide the navbar, so that some items are on the right and some on the left.
Here is the code:

menus.yaml:

main:
  - name: Features
    weight: 10
  - name: About us
    weight: 20
  - name: Log in
    weight: 30  

and params.yaml looks like:

# Site header
header:
  navbar:
    enable: true
    blox: "navbar"
    align: "left"

So I need to put Features and About us on the left, and Log in on the right.
Does anyone know how to do it? Thank you.
