Fixierter Header für mobiles Menü

Hey alexanderb135,
I believe that you are asking for a sticky mobile header, please see our documentation: Sticky header on mobile
Try this CSS in your Enfold Theme Options ▸ General Styling ▸ Quick CSS field:

@media only screen and (max-width: 767px) {
  .responsive #top #main {
    /* Margin top value should be equal to header height*/
    margin-top: 180px;
  }
  .responsive #top #wrap_all #header {
    position: fixed;
  }
}

Please ensure to copy the code from the forum and not an email notification so the symbols are not converted.
After applying the css, please clear your browser cache and check.
If this doesn’t help please include an admin login in the Private Content area so we can be of more assistance.

Best regards,
Mike
