title: Dropdown Menu in WPF Toolbar
body: <p>Having some layout frustrations in WPF- I'm using a ToolBar to house a set of controls, most of which are Buttons and one of which is (going to be) some sort of dropdown menu. In WinForms, the ToolStripDropDownButton was perfect; however, I can't seem to figure out the best way to replicate this behavior in WPF. </p>
  
  <p>Any ideas?</p>
