As it stands, the dropdown is only opened when I click the drop down button, and not when I click anywhere on the box. I have looked at the source code and I am trying to determine what to tweak in order to correctly enable this behavior.
My best guess was to try:
<Trigger Property="IsFocused" Value="true">
<Setter Property="IsDropDownOpen" Value="True" />
</Trigger>
in the ControlTemplate triggers inside of the Template of <Style x:Key="{x:Type editors:PartEditBox}" TargetType="{x:Type editors:PartEditBox}">,
but that did not work
