title: What is Angular Directive for pop-up menu please?
body: <p>I have a web application to write and in the majority of cases I have a 1 to 1 relationship between objects of Class A and objects of Class B, so I hop from one to the other.  Sometimes it is 1 to many, in this case I need to display a popup menu and let the user take a selection from the menu and then I will navigate as if it was 1 to 1.</p>
  
  <p>All this is brand new code so no legacy JavaScript/J Query exists.</p>
  
  <p>I seldom write web code but from I have learnt recently Angular appears to be an architectural correct way to do things instead of writing my own JavaScript I want to use the correct Angular method.</p>
  
  <p>But I need a start point.  I was looking for a Angular directive and I can see things like input[email] and input[month] but I cannot see input[dropdown] or input[popup].</p>
  
  <p>Can someone please steer me in the right direction?  Thanks.</p>
