Dock and undock panels and panel groups
You can move panels and panel groups as necessary, and arrange them so that they are floating or docked in the workspace.
Most panels can be docked only to the left or the right of the Document window area in the integrated workspace, while others (such as the Property inspector and the Insert bar) can be docked only to the upper or lower edge of the integrated window.
Note: You cannot
undock the Files panel if you are in Expanded mode. To collapse
the Files panel before undocking, click the Expand/Collapse button-—the
right-most button at the top of the panel. If you close the Files
panel while it’s undocked, it disappears from the interface. To
retrieve it, press F8 or select Window > Files.
Undock a panel group
Drag the panel group by its gripper 
(on
the left side of the panel group’s title bar) until its outline
indicates that it’s no longer docked.
Note: If you undock the Property inspector, its format
changes so that it no longer has a gripper bar or title bar, but
you can click anywhere on the panel to drag it or redock it.
Minimize or restore a panel or panel group
Redock a panel or panel group
Drag the panel group by its title
bar to the left or right sides of the workspace until you see a
dark black outline appear, and then let go. You may have to drag it
upward to get the black outline so you can add it to the set of
panels already displayed.
Note: Some panels, such as the Property inspector and Results,
must dock above or below the Document window, not to the left or
right.
Dock a panel group to other panel groups (floating workspace) or to the integrated window (Windows only)
Undock a panel from a panel group
Select Group With >
New Panel Group from the Options menu 
in the
panel group’s title bar. 
You can also undock a panel by dragging
it out of the panel group.
