Disable Specific Parent Link without affecting similar submenu Labels
this will disable Research Link,
we could have used the following
// About Eei Link disabled
jQuery("#menu-main-menu a:contains('Research')").click(function(e) {
e.preventDefault();
});
But that will also disable any submenu items or other parent links that CONTAIN "Research"
instead specify the ending of the URL and disable link with CSS
jQuery('#menu-main-menu a[href$="/research/"]').css("pointer-events", "none")
