 form do |f|
    f.inputs do

       .....

      f.input :Category,:input_html => {
        :onchange => remote_request(:post, :get_child_category, {:child_category_id=>"$('#blog_category_id').val()"}, :child_category_id)
      }
      f.input :child_category_id
       .....
    end
    f.actions
  end

method:-

 controller do
    def get_child_category
      @child_category = Category.where(:parent_id => params[:child_category_id])
      render :text=>view_context.options_from_collection_for_select(@child_category, :id, :name)
    end
  end

application_helper.rb

 def remote_request(type, path, params={}, target_tag_id)
        "$.#{type}('#{path}',
                   {#{params.collect { |p| "#{p[0]}: #{p[1]}" }.join(", ")}},
                   function(data) {$('##{target_tag_id}').html(data);}
         );"
    end

is there any solution? as it's not population sub category dropdown.
