Hi. Thank you for this awesome plugin.
I found a strange issue with the studiopress enterprise theme (don't know if it happens also with others).
As you can test here: http://new.studiosas.it/attivita-e-servizi-alle-imprese/ submenus of the secondary menu (generated by the plugin) are slightly shifted to the right. That doesn't happen with a manually generated submenu with the plugin deactivated.
