I have the Problem that my Dropdown Menu is not working anymore after I made the navigation bar sticky

HTML:

<div class="navbar">
    <a  href="#homeNav" id="home">Home</a>
    <a href="#contact">Kontakt</a>
    <a href="#ueberuns">Über Uns</a>
    <a href="#unserteam">Unser Team</a>
  <div class="dropdown">
    <button class="dropbtn" onclick="leistungen()">Leistungen <i class="fa fa-caret-down"></i> </button>
    <div class="dropdown-content" id="myDropdown"> <a href="leistungen.html#fassaden">Fassadenanstrich</a> <a href="leistungen.html#innenGestaltung">Innengestaltung</a>  <a href="leistungen.html#wärmeSchutz">Vollwärmeschutz</a><a href="leistungen.html#spachtelArbeit">Spachtelarbeiten</a><a href="leistungen.html#weiteres">Weiteres</a> </div>
  </div>
</div>
