    <li class="moj-sub-navigation__item">
      <a class="moj-sub-navigation__link" aria-current="page" href="#1">Nav item 1</a>
    </li>

    <li class="moj-sub-navigation__item">
      <a class="moj-sub-navigation__link" href="#2">Nav item 2</a>
    </li>

    <li class="moj-sub-navigation__item">
      <a class="moj-sub-navigation__link" href="#3">Nav item 3</a>
    </li>
