Hello,

We can reduce the font size of the menu items at the point when the menu is broken:

Please add this code to the Theme Settings > Custom CSS > Global:

@media screen and (max-width:1438px){
body .woodmart-navigation .item-level-0>a {
    padding-right: 5px;
    padding-left: 5px;
}
}
@media screen and (max-width:1329px){
body .whb-color-dark .navigation-style-bordered .item-level-0 > a {
    font-size: 11px;
}
}
@media screen and (max-width:1235px){
body .whb-color-dark .navigation-style-bordered .item-level-0 > a {
    font-size: 8px;
}
}

Best Regards
