How to attach a WYSIWYG editor to Active Admin 2.0?

Question

Ruby on Rails

The project uses the Ruby on Rails gem for the Active Admin 2.0 admin panel.
It is necessary to fasten a simple WYSIWYG editor for the form, tell me how this can be done?
Something like on the skin below, but with less functionality.

Answer 1

Take, say, TinyMCE and integrate it.

ActiveAdmin.register Page do

  permit_params :body, :name

  index do
    column :name
    column :created_at
    column :updated_at
  
    actions
  end

  form do |f|
    f.inputs "Page Details" do
      f.input :name
      f.input :body, as: :text, input_html: { class: "tinymce" }
    end
    f.actions
  end

end
