How can I resize the editor

I have a similar question, but I'd like to make it more narrow. I couldn't find any configuration property to do this.

You can try to add this code to the fck code. (where you insert the code to display)
$oFCKeditor->Height = '100px';
$oFCKeditor->Width = '300px';

If you don't get this to work, you can make your own config file.
When using javascript to create a fck form, you need to write like this.

oFCKeditor.Height = '250px';
oFCKeditor.Width = '350px';

The first suggestion worked. Thank you very much.

In addition, you have the FitWindow property.

try this.

$oFCKeditor->Height = '100%';
$oFCKeditor->Width = '100%';
