How this widget docking are named in Enums?

Hello, can someone say me, what’s Enum name/type of this 5 central docking types?

Here you go. Enum.InitialDockState should be your answer.

I’m looked at this page already. There’s only 5/10 modes:

which I don’t mention in my question on image.

You only asked for 5 docking modes. I don’t think you can get as specific as having 9 or 10 docking modes, pretty sure roblox doesn’t allow that right now.
