Track certain elements on a website (no replies)

Hello,

I'm sucesfully gathering data of visitors, but I would like to get more detailed information on what they do on my website. Currently I only see an entrance and an exist. There are some clickable elements on the pages they are visiting so I'd like to load some code that will register in Piwik.

I have the code from the backend, but is there an example code that someone can provide that would trigger a "Goal". As it stands now, I can only see goals for specifc pages.

Thanks!

SR
