BuddyPress.org

Hoping someone can help me with this. I really want to make a drop down share box like google has once you’re logged in (see Screenie below)

Wanting to know if there is a plugin or a theme that does this out there that I can use for reference. Or if any of you know how I can call the activity box so I can pull into a drop down box.

Thanks!
