TDockTree is a TDockManager descendant with a simple docking manager that allows docking a control into another using Align=alClient to fill the whole client area.
In this class, Docking means: Combining several windows into one. And, a window can be a TCustomForm instance, a floating (undocked) control, or a TDockForm instance. A window can be docked to another to the left, right, top, bottom, or "into". The source docking window will be resized to fit to the target docking window.
A docking manager supporting multiple controls per docksite (aka a layout) can be found in the ldocktree.pas unit.
TAnchorDockManager which supports multiple controls with a more flexible layout, store and restore, and more options can be found in the anchordocking package.
