Hello,
I am trying to build some custom drag-and-drop email templates for clients. When I use the rich text custom module, it appears fine when I don’t have enabled_features in the fields.json. However, when I try to customize the toolbar, the editor in the email builder completely disappears.
At a basic level, I started with the field.json:
[ {
“id” : “f93ddec6-90fe-ffc5-238f-655e63b67d95”,
“name” : “html”,
“display_width” : null,
“label” : “Rich text content”,
“required” : false,
“locked” : false,
“type” : “richtext”,
“default” : “<h2>Something Powerful</h2>\n<h3>Tell The Reader More</h3>\n<p>The headline and subheader tells us what you’re <a href=\”#\“>offering</a>, and the form header closes the deal. Over here you can explain why your offer is so great it’s worth filling out a form for.</p>\n<p>Remember:</p>\n<ul>\n<li>Bullets are great</li>\n<li>For spelling out <a href=\”#\“>benefits</a> and</li>\n<li>Turning visitors into leads.</li>\n</ul>”,
“enabled_features” : [“bold”,“link”,“image”]
} ]
and we end up with this:
missing content editor
However, when I REMOVE the enabled_features array from the fields JSON, the editor reappears:
Can anyone offer insight, or assistance in solving this? 
Thanks!
