#render_create_content_link(element, content_name, options = {}, options_for_content = {}) ⇒ Object

Renders a link that dynamically adds an additional content into your element editor view.

NOTE: You have to define additional contents in your elements.yml file first.

Example:

# config/alchemy/elements.yml
- name: downloads:
  contents:
  - name: file
    type: EssenceFile
  additional_contents:
  - name: file
    type: EssenceFile

Then add this helper into the elements editor view partial:

<%= render_create_content_link(element, 'file') %>

Optionally you can pass a label:

<%= render_create_content_link(element, 'file', label: 'Add a file') %>
