I can’t even get the menu to open on the demo to test, it’s a very basic theme. If you can provide a link to your site I can see if I can adjust the menu using CSS.
Thanks for your reply and offer @themesumo.
I think this is something to fix for @indigothemes because it looks like it’s working in the ‘pro’ theme by giving the menu a max-height and overflow-y: auto;.
This problem should be fixed in the theme as this use-case could be very common.
@rdd, fixed and updated version is live. Hope this helps. 🙂
@indigothemes It doesn’t seem to be resolved yet.
adding the following css resolved it (more or less) for me.
ul#menu-main {
overflow-y: auto;
max-height: calc(100vh - [header height]);
}
