title: Generate list of parents-childs (recursive relationship) from Dataset
body: <p>I'm trying to build a list (HTML) with a recursive relationship.  The data is in a dataset but could converted to a data table if it's easier.</p>
  
  <p>I don't know what's the best option to achieve this.  I was thinking about using nested repeaters.</p>
  
  <p>Here's the data: </p>
  
  <pre><code>__ID__ | __NAME__  | __PARENT__     | __LEVEL__ 
  1      | Patrick   |                | 1           
  2      | Mark      |                | 1
  3      | Scott     | 2              | 2
  4      | Jason     |                | 1
  5      | Julian    |                | 1
  6      | John      | 6              | 2
  7      | Steve     |                | 1
  8      | George    | 1              | 2
  9      | Robert    | 1              | 2 
  10     | Rodney    | 8              | 3
  </code></pre>
  
  <p>Here the output I want to produce</p>
  
  <pre><code>- Patrick [1]
    - George [8]
      - Rodney [10]
    - Robert [9]
  
  - Mark [2]
    - Scott [3]
  
  - Julian [5]
    - John [6]
  
  - Jason [4]
  
  - Steve [7]
  </code></pre>
