I have a slate window (having some content) opening from a button pressed.
Now i want to make it Dockable
**Aspected Behaviour !
**
my window is dragable and i want when i drag it to the left untill a threshold reached
a place holder with specific width and full height showing on the most left side and upon releasing the window, it should be Docked with specific width/height i.e (250/full height).
and when i click on this docked window and drag it to the right it should become floating window again.
All this behaviour i want just inside game viewport so that it should be working only inside game viewport.
I mean for unreal docking system not for OS docking system.
