TinyMCE is an excellent WYSIWYG editor. The same can be used in rails with this plugin. In many cases, we need to toggle tinymce editor on/off. For this add the following lines to tiny_mce_helper.rb file of your plugin just before javascript_tag tinymce_js line in tiny_mce_init method.

tinymce_js += %Q! function toggleEditor(id) {
    if (\!tinyMCE.getInstanceById(id))
        tinyMCE.execCommand('mceAddControl', false, id);
    else
        tinyMCE.execCommand('mceRemoveControl', false, id);
    }
    !

And you can easily place a link beside your editor to toggle something similar to:

<%= link_to_function "Add/Remove Editor", "toggleEditor('name')" %>

Here name is the name of the textarea/textbox to which you are applying tinymce editor.

Recent releases of tinymce would require to use tinyMCE.get(id) instead of getInstanceById(id) in code above.
