title: selenium (phpunit) click on drop down link
body: <p>I want be able click on link from drop down using selenium with phpunit. I don't have any idea how make it happens, can anyone show me example or relevant tutorial, post or anything that can help me figure out.</p>
  
  <p>when I try click on the element without put mouse over the drop down I got this error:</p>
  
  <p><strong>Element is not currently visible and so may not be interact with command ....</strong></p>
  
  <p>Thanks.</p>
  
  <p>EDIT:
  when I said "drop down" I don't mean regular select. it more like popup 
  you can see the example here:
  <a href="http://investing.com" rel="nofollow">http://investing.com</a></p>
  
  <p>look how they build the menu I want be able click on 'Technical' -> 'Fibonacci Calculator' for example. </p>
