# Shared Toolbar and Bottom Bar Documentation

The optional Shared Space plugin makes it possible to share the same editor toolbar and bottom bar among several CKEditor instances.

## Classic Editors Sharing Toolbar and Bottom Bar

For each editor instance you can define the elements that will be shared. In the example below two classic editors are combined, sharing the same toolbar and bottom bar. This is possible thanks to the config.sharedSpaces configuration setting.

## Inline Editor with Shared Toolbar and Bottom Bar

Inline editors can also be configured to share the toolbar and bottom bar (it is in fact possible to use a mix of classic and inline editors together as well). One of most interesting use cases for the Shared Space plugin is the possibility of providing an improved fixed user interface for the inline editor:

# Apollo 11

Apollo 11 was the spaceflight that landed the first humans, Americans Neil Armstrong and Buzz Aldrin, on the Moon on July 20, 1969, at 20:18 UTC. Armstrong became the first to step onto the lunar surface 6 hours later on July 21 at 02:56 UTC.

Armstrong spent about three and a half two and a half hours outside the spacecraft, Aldrin slightly less; and together they collected 47.5 pounds (21.5 kg) of lunar material for return to Earth. A third member of the mission, Michael Collins, piloted the command spacecraft alone in lunar orbit until Armstrong and Aldrin returned to it for the trip back to Earth.

There are a few important benefits of using the Shared Spaces plugin to provide inline editor with fixed UI instead of using the Div Editing Area plugin for the same purpose:

• No additional nested <div> elements surrounding the editing area are needed — the original element that stores the content is used for editing. This means that styles applied to content after it is loaded into the editor stay exactly the same, providing real WYSIWYG experience with no surprises.
• The Auto Grow feature is not really needed, as the size of container can be easily controlled with CSS.
