Hi there,
Thanks for updating the thread! You can add this under Custom > CSS in the Customizer or in your child theme’s style.css file.
body .x-navbar .desktop .sub-menu a:hover {
color:#000000;
background:#ffffff;
}
or if you don’t want the underline to be so close to the text, more similar to your example link use the following instead:
body .x-navbar .desktop .sub-menu a:hover {
color:#000000;
background:#ffffff;
text-decoration:none;
}
body .x-navbar .desktop .sub-menu a span:hover {
border-bottom: 1px solid #000000;
}
Hope this helps – thanks!
