Mobile Menu Slide In From Top

Hey!

Try adding this code to the Quick CSS:

#mobile-advanced{
  right: 0;
  top: -100%;
  -webkit-transform:  scale(1);
  -moz-transform:   scale(1);
  -ms-transform:    scale(1);
  transform:      scale(1);
  -webkit-transition: all 0.3s ease;
  -moz-transition:  all 0.3s ease;
  transition:     all 0.3s ease;
  -webkit-transform-origin: 0% 0%;
  -moz-transform-origin: 0% 0%;
  -ms-transform-origin: 0% 0%;
  transform-origin: 0% 0%;
}

.avia_transform3d #mobile-advanced{
  -webkit-transform:  scale3d(1);
  -moz-transform:   scale3d(1);
  transform:      scale3d(1);
}

.show_mobile_menu #mobile-advanced{
  -webkit-transform:  scale(1);
  -moz-transform:   scale(1);
  -ms-transform:    scale(1);
  transform:      scale(1);
  -webkit-transform:  translate(0, 100%);
  -moz-transform:   translate(0, 100%);
  -ms-transform:    translate(0, 100%);
  transform:      translate(0, 100%);
}
.avia_transform3d .show_mobile_menu #mobile-advanced{
  -webkit-transform:  scale3d(1);
  -moz-transform:   scale3d(1);
  transform:      scale3d(1);
  -webkit-transform:  translate3d(0, 100%, 0);
  -moz-transform:   translate3d(0, 100%, 0);
  transform:      translate3d(0, 100%, 0);
}

Cheers!
