Showing two windows side-by-side

You can display two windows side-by-side in the main window work area. Switching to one of these windows displays both of them.

The following rules apply to windows that are displayed side-by-side:

• A single window can be displayed side-by-side with exactly one window.
• Docked windows cannot be displayed side-by-side with other windows. 

To show two windows side-by-side, run one of the following commands: Show side-by-side (vertically)/Show side-by-side (horizontally), and then select a window. These commands are available in the following menus: 

• System commands area, the Dock/Show side-by-side with another window button.
• Main menu, the Windows section.
• Context menus of form titles and context menus of the items on the opened items panel.

You can also use the Show side-by-side with the current window (vertically)/Show side-by-side with the current window (horizontally) command of the context menus of items in the opened items panel.

The commands perform the following actions:

• Show side-by-side (vertically). The second window is displayed to the right of the first one. If the command is executed from the context menu of an inactive window, it becomes active.
• Show side-by-side (horizontally). The second window is displayed below the first one. If the command is executed from the context menu of an inactive window, it becomes active.
• Show side-by-side with the current window (vertically). The current window is displayed on the left.
• Show side-by-side with the current window (horizontally). The current window is displayed at the top.

To show windows separately, right-click the form title or the item of the opened items panel, and then click Undock/Show separately.
