I'm new at C5. I purchased a template and am building a church site. I had someone help me put everything on the server and make the template C5 friendly. Right now for my nav bar I am using the auto-nav C5 block. I would like to know how to add a drop down menu. My template came with dropmenu.css, but I'm not sure how to make all this work. Do I have to use C5 to get the dropdown menu to work, or through the css?

Any help would be appreciated. Thanks!
