I have a taxonomy view that displays children of a parent taxonomy.
I have successfully output the taxonomy description using the shortcode in the view loop editor: [wpv-taxonomy-description]
However, I cannot get the description to render as html, despite being entered into a WYSIWYG editor on the taxonomy editing page - it just renders as plain text.
I have tried installing the plugin 'Allow HTML in Category Descriptions' but it doesn't make any difference.
My recommendation here is to create a second description custom field and add your description there. This way you won't need to use the [wpv-taxonomy-description] shortcode given that it will render the field without the HTML formatting.
With the second description custom field you can render it with the HTML formatting when using the types shortcode for the Meta field.
