Login Icon/Dropdown Login

How can I create a Login Icon or Text in a module position that drops down into a Login Box? Im looking at my EasySocial Modules and i dont see that option...but I see a few examples in different places..including on THIS site. Am i missing something or do I already have that ability and just overlooking something? I try not to bother you guys so much because you do such a great job I dont want to over tax you.

Thanks
