Recursive cells — is it possible?

menu.html.erb

<%= render_cell(:menu, :show, { contents: @menu_content }) %>

menu_cell.rb

class MenuCell < Cell::Rails
  include Cell::Rails::ViewModel
  include ApplicationHelper

  def show opts = {}
    @options = default_params.merge(opts)
    @options[:contents] = JSON.parse(@options[:contents])
    render
  end

  def default_params
    {
      contents: "[]",
      level: 1
    }
  end
end

show.html.erb

<ul>
  <%= @options[:contents].each do |item|  %>
    <li>
      <%= item["name"] %>
      <% if item.include?("sub_sections") %>
        <%= render_cell(
          :menu, :show, {
            contents: item["sub_sections"],
            level: (@options[:level] + 1)
          }
        ) %>
      <% end %>
    </li>
  <% end %>
</ul>
