There are a few adjustments you need to make for this.
- Select Nav Menu White and
make the right margin -35
and set Max Height to 250
and set background color to what ever you want. I chose pink here so you can see it clearly. - Select Nav Menu Head and add padding right 20
- Select Icon and add padding right 40
- There may be a few more tweaks to get it just right but this should get you going in the right direction.
Adjustments will need to be made separately at each breakpoint.
Obviously you can adjust all these values to get the exact look you need.
Hope this helps.
