UMG Documentation for 4.4 Preview

Hmm still dont get it, if my hierarchy look like :

[CanvasPanel]
-Button1
-[MyBorder]
– [VerticalBox]
— Buttons
-Button

I want to access MyBorder layout so i can move MyBorder within the CanvasPanel

How would i do it the right way?

Update: sry my bad, i read it through more carefully now , ofc i should use MyBorder and then cast it to CanvasPanelSlot and then i can access the correct layout for myBorder
