To make the navbar sticky as you scroll, set the data-sticky-nav attribute to "true". You can also adjust additional settings like if clicking a new tab should scroll back to the top of the tabs, and what that offset amount should be.

<div data-wm-plugin="tabs"
  data-source="/portfolio"
  data-sticky-nav="true" 
  data-scroll-back-to-top="true"
  data-scroll-back-offset="150"
></div>
