Capture New Collection in VIEW in the Loop

[Breno Perucchi]

I need to capture new collection from the object that running in the loop.

I already try this, but don't return array. 

If @categories = ['1','2','3'] 

the new_collection has = "123"

---------------

VIEW

---------------

{% for cat in categories %}

--->  {% capture new_collection %} {{ cat.id | category_children:'1', }} {% endcapture %} <---

   {% for attr in new_collection %}
      <p> attr ID: {{ attr.id }} </p>

   {% endfor %}

{% endfor %}

------------------

LiquidFilter

------------------

  def category_children(id, depth = nil)

    if depth == nil

      @categories = Imentore::Category.find(id).descendants.collect{|category| Imentore::CategoryDrop.new(category)}

    else

      @categories = Imentore::Category.find(id).descendants(to_depth: depth.to_i)

    end

   @categories

  end
