title: Creating a dropdown toolbar in xaml
body: <p>I've recently started working with XAML in WPF and I'm working on someone elses code. I'm trying to rework a drop down toolbar/menu, because of some display issues but the drop down is created as a <code>&lt;Popup&gt;</code>. I feel technically a menu is not really a popup...</p>
  
  <p>So my question is, is it appropriate to ever create sub/drop down menus using the popup tag? Or would it be better suited for <code>&lt;stackPanel&gt;</code> or something else?
  Thanks</p>
