In Windows, toolbars are docked or floating. Docked toolbars are placed at fixed positions around the design area. Floating toolbars can be placed anywhere in the design area. You can undock a toolbar, making it a floating toolbar, and then place it at any location in the design area. Macintosh toolbars are always floating.
You can also right-click the title bar of a floating toolbar and select Hide, or click its Close button.
