title: Show buttons to user to select in botframework
body: <p>I am trying to display buttons for selecting city for user like i have following cities: 
  cleveland, columbus, delaware, mayfield</p>
  
  <p>How can show these as buttons in botframework? I can do this with forms like:</p>
  
  <pre><code>[Prompt("Please select what {&amp;} you are in? {||}")]
  public City? City;
  public static IForm&lt;SandwichOrder&gt; BuildForm()
  {
      return new FormBuilder&lt;SandwichOrder&gt;()
              .Message("Welcome to the simple City bot!")
              .Build();
  }
  </code></pre>
  
  <p>But the app i am creating is not a form and there are no more synchronized questions. So what is other simpler way of showing cities for user to select?</p>
