JUX Mega Menu does not display subcategories on mobile

Hi,

I have installed the JUX Mega Menu module
When I view the form in mobile version it does not open the subcategories for me ( discovercampania.it/esplora-la-campania/territorio/irpinia )

I also tried to add the following code which I found on the forum

@media screen and (max-width: 767px) {
# js-mainnav.megamenu.vertical.left .js-megamenu ul.level0 li.mega .childcontent {
margin-left: 0! important;
}
}

in the file ... modules / mod_jux_megamenu / assets / css / style.css.


Version
Joomla 3.10
JUX Mega Menu 3.3.0

Thanks,
