Hi there,
the way Niche works is by having the Primary Navigation also located in the Off Canvas Panel with the Woo Widgets.
We then use this CSS to hide the nav in the off canvas for desktop:
@media (min-width: 768px) {
.slideout-navigation .main-nav {
display: none;
}
}
and the HTML used to create the filter toggle has the hide-on-mobile
class.
This is the only way you can make off canvas filter widgets work for all devices at this time.
If you want separate menus and separate off canvas filters you will need to add an Off Canvas Plugin
