Question

Hello!

How can I do this:

CKEDITOR.replace( 'editor1',
{
   on :
   {
      instanceReady : function( ev )
      {
         // Output paragraphs as 
Text
.
         this.dataProcessor.writer.setRules( 'p',
         {
            indent : false,
            breakBeforeOpen : true,
            breakAfterOpen : false,
            breakBeforeClose : false,
            breakAfterClo`enter code here`se : true
         });      
      }
   }
