Out of the box, Modern will cause significant residual styling and break UberMenu. However, because the theme provides a pluggable menu function, it is very easy to completely replace the theme’s menu with UberMenu. Just add the following PHP to your child theme’s functions.php
to replace the theme’s menu:
function wm_navigation(){ if( function_exists( 'ubermenu' ) ){ ubermenu( 'main' , array( 'theme_location' => 'primary' ) ); } }
