Jux mega menu css - mobile phone

Hi
Thank you for feedback us
About your problem, Because the position menu set below so off canvas is not possible to bring up
I will instruct you custom it, in back-end module -> tab Advanced -> Custom CSS and add code:

@media screen and (max-width: 768px){
.js-megamenu-off-canvas {
top: -310px!important;
}
}

Hope it will help you
Thanks
