BuddyPress.org

Hi there, thanks for your help in advance, I am amending css in buddypress.css to hide top menu in profiles, as i have my own. But I want to keep top menu in groups. How would I do this? Here is my code for the removal of the menu. What would I add to it to make it only for profiles, or how could I exclude .groups.single-item#object-nav from the display: none?

#buddypress div.item-list-tabs#object-nav ul li {
display: none;

Thanks so much for your help 🙂
