#13967 confirmed Bug

sharedspace create div's with duplicated ids

Steps to reproduce

I suppose it's good practice not create duplicate ids in an html document, but ckeditor 4.5.5 + sharedspace is doing just that.

the following html demonstrate the error:

<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">

<div id="top-ck-toolbar">
    <!-- ckeditor top toolbar is rendered here -->
<div id="bottom-ck-toolbar" style="position: fixed;bottom: 0;width: 100%;">
    <!-- ckeditor bottom toolbar is rendered here -->

<div id="content-ck">
    <textarea id="mytextarea"></textarea>
    <!-- ckeditor editable area is rendered below -->

<script src=""></script>
<script src=""></script>
    var ckeditor_config = {
        extraPlugins: [

        sharedSpaces: {
            top: "top-ck-toolbar",
            bottom: "bottom-ck-toolbar"
        on: { // execute after ckeditor full load
            instanceReady: function (evt) {
                //by default, ckeditor create a div with the id is named "cke_" + ID_OF_TEXT_AREA

                var elements_with_same_id = $('[id="cke_mytextarea"]');

                $(elements_with_same_id[0]).css({border: '3px solid rgb(183, 172, 19)' });
                $(elements_with_same_id[1]).css({border: '3px solid rgb(43, 183, 19)' });
                $(elements_with_same_id[2]).css({border: '3px solid rgb(183, 19, 19)' });
                alert("number of duplicated elements with 'cke_mytextarea' id: "+ elements_with_same_id.length);


    //start ckeditor
    CKEDITOR.replace("mytextarea", ckeditor_config);


Expected result

No generate duplicate ids.

I would suggest that ckeditor "top toolbar" and "button toolbar" should be id prefixed, respectively, "cke_toolbar_top" and "cke_toolbar_button".

Then, in case I have a textarea with id "mytextarea", the generated id to "top toolbar" and "button toolbar" is respectively, cke_toolbar_top_mytextarea" and "cke_toolbar_button_mytextarea".

this is related issue #10436, but my problem is different.

  • in the case of #10436, the id already exists in the DOM and ckeditor generete a new element with the same id.
  • in my case, there is no element with id duplicated in the DOM, but ckeditor shared space will create "top toolbar", "button toolbar" and div container of editable area with the same id

I was able to reproduce this problem from CKEditor 4.1 in every browser (tested also without jQuery).
