I am using the component Engage Box and require a Joomla menu item to open content.

However, it appears the template or a 3rd-party extension (Helix Ultimate) does not include a unique CSS class on the specific menu item ("Services"). See demo website - http://janadians.com/faceypartners/

The developer of Engage Box says that we need to specify a unique class to that menu item so it can work. If not we could use something like - .sp-megamenu-parent > .sp-menu-item:first-child

How can this be done?
