I need to disable/hide a submenu under Opportunities. When I open an Opportunity, I see a submens for "CRM Comprehensive Notes". I cannot find this submenu anywhere, however, to hide it. I exported the sitemap.xml and looked in customizations but cannot find this link.
var removeLeftNav = function(navAreaToRemove)
if (document.getElementById(navAreaToRemove) != null)
document.getElementById(navAreaToRemove).style.display = 'none';
