I have created a Widget, which inserts a form, with a WYSIWYG editor.
But the WYSIWYG editor in the Catalog Section, doesn’t provide the Widget button on its editor.
I tried pasting the widget code {{widget type="module/widget_name"}}, into the description area, but it didn’t work.
I have written a short tut, on how to enable the mentioned feature:
