How to hide toolbar in CKEditor inline - ckeditor

Question

I have an application that needs the inline CKEditor but without toolbar. For the inline CKEditor part I have:
CKEDITOR.disableAutoInline = true;
var editor = CKEDITOR.inline('editable', {on: {
instanceReady: function() {periodic();}
}});
var periodic = (function() {
var data, oldData;
return function() {
if ((data = editor.getData()) !== oldData) {
oldData = data;
$.post("update.php", {txt:data});
}
setTimeout(periodic, 1000);
};
})();
Then for the toolbar hiding part I found this: CKEditor 4 Inline: How to hide toolbar on demand?
//Whenever CKEditor loses focus, We will hide the corresponding toolbar DIV.
function hideToolBarDiv(event) {
// Select the correct toolbar DIV and hide it.
//'event.editor.name' returns the name of the DIV receiving focus.
$('#'+event.editor.name+'TBdiv').hide();
}
Problem is that I have no clue how to combine these two together :) I appreciate for any hint. Thank you.

Answer 1

I found another link that seems to solve my problem: Can I use CKEditor without a toolbar?
The script seems to be working alright though I am still not sure if it is a correct way to do it:
CKEDITOR.disableAutoInline = true;
var editor = CKEDITOR.inline('editable', {
removePlugins: 'toolbar',
allowedContent: 'p h1 h2 strong em; a[!href]; img[!src,width,height]'
on: {instanceReady: function() {periodic();}}
});
var periodic = (function() {
var data, oldData;
return function() {
if ((data = editor.getData()) !== oldData) {
oldData = data;
$.post("update.php", {txt:data});
}
setTimeout(periodic, 1000);
};
})();

In my eyes, I have done it in two ways:
1) Using the removePlugins option and just remove the toolbar:
CKEDITOR.inline( 'textarea', {
removePlugins: 'toolbar'
} );
here, you can also use allowedContent to allow the contents for ACF
CKEDITOR.inline( 'editable', {
removePlugins: 'toolbar',
allowedContent: 'p h1 h2 strong em; a[!href]; img[!src,width,height];'
} );
2) Using CSS - Not the standard approach: (little tricky)
Just make css to display:none the toolbar, like
.cke_inner {
display: none;
}
Hope it will help someone.
