title: How to Create a Hierarchy of Elements Generated Automatically in Sparx Enterprise Architect
body: <p>I am using Sparx Enterprise Architect for the modeling process. </p>
  
  <p>I created a custom requirements toolbox which is called security requirements based on a list of security standards using MDG technology. </p>
  
  <p>I would like to create a hierarchy of requirements once the user drag-and-drop the main element into the workspace all sub-elements (requirements) are displayed automatically. </p>
  
  <p>How I can create or design something similar to this process. </p>
  
  <p>Thanks, </p>
