I need to add the widget button to the WYSIWYG editors of some category attributes.

There are two questions on Stack Overflow with accepted answers:

The one problem: this solution doesn't work 100% (tested on EE and CE

What's the problem?

If you set the config entry add_widgets to true (btw, you can do that by observing the event cms_wysiwyg_config_prepare, that's better than rewriting or overwriting the helper block), the widget buttons are displayed. That's fine.

You can even use the "Insert Widget..." button outside the WYSIWYG Editor. That's good.

The problem is the widget button in the WYSIWYG editor: you can click on it, the widget manager opens but when you select a widget type, the configuration area doesn't open.

That's the button not working

Empty configuration page

The reason is that there is a JavaScript error happening:

"HierarchyRequestError: Node cannot be inserted at the specified point in the hierarchy"

Javascript Error

Even after debugging for some time I didn't find out how this can be fixed. Did somebody of you already solve that problem?

    Do you have a ready to go module for this that reproduces the behavior? I'm happy to take a look if I've got a reproducible test case. – Alan Storm Jul 30 '13 at 4:02
  • Sorry Alan, I totally missed your comment. oserk posted an extension that does it pretty similar. Please note my comment there: the widget button seems to work in Chrome 28. Thanks for your offer to help! – Matthias Zeis Aug 13 '13 at 17:29
  • Struggling with this one, too. Have you found a solution in the meantime? – nevvermind May 8 '14 at 11:07


I have created this module for you.

This works for me!



  • It works fine on my end, and I suppose that some other js conflict is in frontend .. I have tested my module on ce version – Kresimir Pendic Aug 13 '13 at 11:41
  • Thanks for your effort, oserk. It seems that both your module and my original code now work with Chrome 28 but that it still doesn't work with Firefox 23 (Windows). Is it the same for you? – Matthias Zeis Aug 13 '13 at 17:27
  • Link is now dead, don't suppose you still have this floating about do you @oserk? Thanks. – zigojacko Mar 3 '14 at 12:28
  • Ohh, I was clening my github account and I guess did delete it, will check it out to see if got it home and will update it here.. – Kresimir Pendic Mar 3 '14 at 15:25

Although I didn't find the reason I can confirm that it now works (at least) in EE and Firefox 33. Resolve the problem by updating Magento and/or your browser to the current version.
