How to add css class to .qa-nav-sub-list in php?

Question

I'm trying to add 2 classes to ul.qa-nav-sub-list. This is the menu that displays for the admin under the main nav. It's created dynamically using $navtype, but i can't figure out where to add my classes so they aren't added to the rest of every $navType. Thank you!

Change the below HTML code to what you want accurately. In some cases, we may be able to write the answer.

<ul class="qa-nav-sub-list">
  <li class="qa-nav-sub-item qa-nav-sub-admin-general">
    <a href="../admin/general" class="qa-nav-sub-link">General</a>
  </li>
  ...
</ul>

=> What is the final HTML code you want??
