title: How do I disable the opening and closing animation of the DropDown of a ComboBox in WPF?
body: <p>When I put a combobox in my WPF app, at runtime, when I click it, it rolls down the included items. After selection, it rolls the DropDown up again.</p>
  
  <p>Is it possible to prevent the rolling animation from happening? Instead I'ld like to just have it open and closed immediately.</p>
