title: Angular way to open and close panels
body: <p>In Angular if I had a few panels, similar to tabs how do you open the panel on click and animate it up, if I click a different panel new html is loaded in, but if I click an open panel it needs to animate down.</p>
  
  <p>Almost exactly like <a href="http://plnkr.co/edit/?p=preview" rel="nofollow">http://plnkr.co/edit/?p=preview</a> however 3 of them.</p>
  
  <p>I've looked at both ngRouter and UI-Router, I think UI-Router is closer to what I need because you can remove a view.</p>
