Hi deftosxromata
It due to this CSS code on your site:
.ja-megafilter-wrap .ja-mg-sidebar {
height: 50px;
overflow: hidden;
width: 100%;
}
which set the height to 50px only, we don't have this code by default.
You can override it by this:
@media (max-width: 768px) {
.ja-megafilter-wrap .ja-mg-sidebar {
height: auto !important;
}
}
