  <p>Hello - </p>
  
  <p>The code above is an example of flask-admin page that I am trying to create. The goal is to have on Child's create page a text box for name and a drop down to select a parent. </p>
  
  <p>With the above setup, there is only name field. The parent drop down box is missing.</p>
  
  <p>Any ideas how to make it happen?</p>
