I am facing a problem regarding my drop down menu items

Web address: https://cheapwebboost.com
Issue:
My drop-down items under “Service” are PPC and SEO etc. They open right bellow the service and not after the borderline of nav-bar means the service items overlap with my nav-bar. If, I fix this issue by giving a margin-top: 11px; then this issue of overlapping gets resolved but my items under service becomes unclickable as they disappear so quickly. Same is the case with “resources” and its dropdown item blog…Please help…whats wrong in it…
