title: How to implement a navigation bar in angularjs
body: <p>Starting with angularjs as a newbie I have created a navigation bar. It has several sub menus. But I am not completely sure what is the best practice to deal with it using angularjs. I would like to keep track of the current selected menu item to make it 'active' and change the rendered template depending on the selection.</p>
  
  <p>I am looking for some examples or some example code, that can be used in production environment. </p>
  
  <p>Sorry for this very generic question, but I hope someone can help me. </p>
