Controlling List Ordering for Component Dialog Box

That sounds simple enough but for some reason I cannot affect it.

Am pretty green with Sketchup. Not even exactly sure what you mean by “Outliner”.

What are the actual mechanics of selecting the sub_component?’

Each of my sub_components has Size & Position Attributes.
I have tried right-clicking on the collapsed sub_component titles and dragging with the mouse button down and I have tried it with the attributes on display but nothing seems to move the dial?

Which part of the dialog box do you click on to make this happen?
