Adding A Title To The Onclick-Dropdown Wrapper

I'm having trouble doing this. I cant figure out how to add a title the the onclick-dropdown wrapper.

I've tried looking on, cant really find what I need.

I compared the sidebox wrapper tpl file to the onclick tpl and saw that there was no header class.

So I copied the header class from the side wrapper to the onclick tpl file and then made a style in the styles.css file. Changed the header class style name to the one I created in \my styles.css and cant figure out anything past that.

I don't even know if that was what I was suppose to do.

Just simply want to add a title to our drop down wrapper box.
