Ok, I'm officially stuck on this one.

I created a nice screenpart that expands/collapses a table to show/hide rows of the table.

However, now when I add it to the scene on an iPad, and place an orange rectangle beneath it, I can't figure out how to make the rectangle move down when the table is expanded by tapping the More button.  It appears that only a single animation can be attached to an interface element, and since I already used the tap action in the Screenpart to do the expand/collapse action, I now cannot use that tap action to also move the orange square downward when the table expands.

It seems what's needed here is the ability to assign an additional action to the More button, but I don't know how to do that.
