Tom very quickly wrote back to me with a fix. Which I now share:
Add the following to the custom CSS in the theme…

#{$wrap} #{$menu} {
> li.mega-menu-megamenu > ul.mega-sub-menu li.menu-item > a {
padding: 3px;
display: block;
}

> li.mega-menu-megamenu > ul.mega-sub-menu li.menu-item > a:hover {
background: red; /** background color **/
color: white; /** font color **/
}
}

and, just so you can see what I was trying to achieve, in case you have an idea how I can do it… – https://phillipdrawbridge.com/images/megamenu.jpg

I want a mega menu, with an image, a bit of blurb in a text box and then two columns of links. Which are currently custom menus. I really like how this looks. The image is static, it’s just pure coincidence that I was on that product page when I did the screen shot.

I found an older thread with someone trying to do the same thing. Looks like it wasn’t possible back then. I’m guessing still not. Maybe, once I know the plugin better, I’ll be able to work out something different.

Thanks for the quick reply. At least I know i’m not being stupid.
