Custom node field type should also support content block; what should I do? I'm using the Paragraphs module for nodes. Here is a quote from its project page:


  Paragraphs module comes with a new "paragraphs" field type that works like Entity Reference's. Simply add a new paragraphs field on any Content Type you want and choose which Paragraph Types should be available to end-users.


But the type is not in the add select on admin/structure/block/block-content/manage/basic/fields/add-field.

It would be nice, if this module could offer the paragraphs field type also for Content Blocks (or other field type creating modules their types).

Has someone an idea, what the module maintainer has to do along general lines? I want to ask this as a feature request in the module's issue queue. But it would be nice if I can give some hint to the maintainer.
From looking at the code, the module does not define a field type. It just defines a widget for entity reference fields.

So, what you need to create instead is an entity reference field that points to paragraphs, and then select the Paragraps widget on "Manage form display".

But that should be exactly the same for nodes as well?
