How to manually add extra navigation next to logo

Site URL: http://s15.squarespace.com

Hey everyone! Can you help? 

I'd like to add two extra links to my header bar, next to my site logo. (NB: While my main navigation hamburger bar remains put on the right.)

Just like www.dropbox.com (see attached screenshot showing the two links "For Teams" and "For Individuals" next to the logo.)

I attach my current layout, as well as a "Design Mockup" showing the two links I'd like to add ("For Kids" and "For Adults"), with the one link faded to show that it's the active page.

Thank you so much!

What is access password? I Guess you can use SS 7.1 to create this layout?

Hi Tuanphan. Thanks for responding. It's "swallow15_pw".  Yes, I am using 7.1, but can't figure out how to have two text navigation links next to the logo, which are not effected by navigation style tweaks for those links on the right.

E.g. I would still want to the burger bar to appear to the right for the rest of the links.
And, eventually there will also be a "log in" link to the right, like that of Dropbox.com.

I hope that all makes sense!
