where to set CKEDITOR.config.allowedContent

You can set it in config.js and on the page itself where the editor is located (prefered method). Here's a sample page. Check the source to see how it's done. 

Here's the guide about setting configuration.

I have the same problem and dont find an answer :(

In the input field/textarea form all works perfekt - so if i creat an "modern" inline editor my html tags where replaced automatical.

here is my code:

html File:

                
    <!-- Load CKEditor -->
    <script src="./ckeditor/ckeditor.js"></script>

	<script>
		CKEDITOR.on( 'instanceCreated', function( event ) {
			var editor = event.editor,
				element = editor.element;
				
			if ( element.is( 'h1', 'h2', 'h3' ) || element.getAttribute( 'id' ) == 'taglist' ) {
				editor.on( 'configLoaded', function() {
				editor.config.toolbar = [{ name: 'document', items: [ 'Bold', '-', 'Italic', '-', 'Underline', '-', 'Strike', '-', 'paragraph', '-', 'Image','Source'] }];
				});
			}
		});
		</script>




<p id="content_part" contenteditable="true">
                  Lorem Ipsum....
                </p>

and this is my configuration file with config.allowContent which is not working

CKEDITOR.editorConfig = function( config ) {

	config.allowedContent = true;
	config.extraPlugins='htmlbuttons'; 

	config.htmlbuttons = [
	{
		name:'button1',
		icon:'icon1.png',
		html:'<p class="special">Hint: It´s a simple warning Field.</p>',
		title:'Special'
	}
];
	
};

Please give me a hint - im searching since 3 hours :(

Thanks
