CKEditor adds extra  tag CKEditor inserts extra &lt;p&gt; tags when users enter a newline.

How do I disable this automatic paragraph tag?
You need to modify these settings to CKeditor.

// The writing rules for the &lt;p&gt; tag.
writer.setRules( 'p', {
// Inserts a line break after the &lt;p&gt; opening tag.
        breakAfterOpen : true,
}


This can either be set programmatically, via JS or I believe you should be able to add it directly via the UI, if you visit the Ckeditor settings page, there should be a box where you can enter ckeditor settings.
