I am trying to animate (slide down) the list that pops up when in the "open"
state of the ComboBox or DropDownList in Spark.
I am defining a custom Skin for that and I guess should deal with the popUp of
the PopUpAnchor. Since the PopUpAnchor is "attached" to the root, when
animating it is fully visible and stays on top of all the content I have on the
page. There is a "useful" comment for me in the default skin, but whatever I
tried it didn't work...
<!---
The PopUpAnchor control that opens the drop-down list.
<p>In a custom skin class that uses transitions, set the
<code>itemDestructionPolicy</code> property to <code>none</code>.</p>
-->
Is there any workaround for slide down animation of the popup list ? Tried
masking it, no luck...
