  <nav class="nav-main">
    <div class="nav-container">
      <ul>
        <li><a href="">About Us</a></li>
        <li><a href="">Services</a></li>
        <li> <a href="#">Careers</a>
          <ul>
            <li><a href="#" class="back">Main Menu</a></li>
            <li class="nav-label"><strong>JOBS IN AMERICA</strong></li>
            <li><a href="">Accountant</a></li>

            <li><a href="">Human Resources Specialists</a></li>
            <li><a href="">Loan Officer</a></li>
            <li><a href="">Reporter</a></li>
            <li class="nav-label"><strong>JOBS IN GERMANY</strong></li>
            <li><a href="">Budget Analyst</a></li>
            <li><a href="">Carpenter</a></li>

            <li><a href="">Financial Analyst</a></li>
            <li><a href="">Human Resources Specialists</a></li>
            <li><a href="">Loan Officer</a></li>
          </ul>
        </li>
        <li><a href="">Downloads</a></li>
