I'm looking to change the init of TinyMCE for Magento admin.

I'm just not satisfied with the default options and want to give my client a more user-friendly way of working with. So I want to remove some plugins, change some options and perhaps add some other plugins. But I want to keep the integrated Magento functionality.

I have not yet found a way to acomplish this without editing the js/mage/adminhtml/wysiwyg/tiny_mce/setup.js directly.

Is there a working solution?


Tobias' solution works very well! As you can read below, I had some trouble getting it to work due to 403 forbidden errors on my localhost. On my staging server however it worked as expected.

After some more testing, I found that the Fooman_Speedster extension I had installed was the cause of the problem. After disabling that, everything works fine!

You can esily create your own module (depends on Mage_Adminhtml) which is extending that js file:


<?xml version="1.0"?>


In your layout file you add a custom js to the header:

<?xml version="1.0"?>
        <reference name="head">
            <action method="addItem">

And in the new setup.js you can overwrite the prototype object:

(function (getSettings) {
    tinyMceWysiwygSetup.prototype.getSettings = function (mode) {
        var oSettings = getSettings.call(this, mode);
        oSettings.extended_valid_elements = "article[class]";
        return oSettings;
  • Thank you for you answer! Looks like it's the way to go. However, when I follow your instructions, I'm getting a network error 403 forbidden on the /skin/m/... url. Do you know what I might be doing wrong?

  • what's the exact name of your file and where did you store it?

  • I've given it the name application_adminhtml/tiny_mce/setup.js. When I inspect with firebug, the file is included as /skin/adminhtml/base/default/application_adminhtml/tiny_mce/setup.js - which is directly reachable via browser. As content I just have an alert('...'); statement in the file - but changing or deleting the content has no effect on the error.

  • Ehm there seems to be a typo or something like that. in your first comment you wrote that you get a 403 on /skin/m/ ... what's the m? in your second comment there's no m mentioned

  • There's no typo, but perhaps I could've been clearer. Magento aggregates multiple files into one call. The full url is quite long so I had to trim it: https://www...com.dev/skin/m/1401549822/js/prototype/prototype.js,/js/extjs/fix-defer-before.js,/js/prototype/window.js,/js/scriptaculous/builder.js,/js/scriptaculous/effects.js,/js/scriptaculous/dragdrop.js,....,/skin/adminhtml/base/default/application_adminhtml/tiny_mce/setup.js
