Hello,
Sorry for the delay.
For now, there is no way to create additional fields for the drill-down menu, use the code below to apply styles to the 2nd and 3rd level drill-down menu.
.mobile-nav .wd-sub-menu.wd-drilldown-show li a {
font-weight: 500 !important;
}
/* 3rd level */
.mobile-nav .sub-sub-menu.wd-drilldown-show li a {
font-weight: 500 !important;
}
You can leave a future request here about those additional fields – https://woodmart.canny.io/feature-requests
Kind Regards
