Showcase: Menu not compatible with Connections Plugin?

While using CONNECTIONS BUSINESS DIRECTORY (, the menu is getting hidden by the directory page content, while it should be overlapping the content and should be visible all the time. thus few last menu from the list are not clickable after certain height.

I tried that and deactivated the plugin for the moment, but if you want to see the example then i can reactivate it on members pages.
The body containing the details of the member is overlapping the sub-menu bar and its child list.
