title: Magento 2.1 Custom module relationship
body: <p>I developed few custom modules for my Magento 2.1 store for smart manegmant of content in some of the CMS pages.</p>
  <p>I used this tutorial <a href="https://www.ashsmith.io/magento2/module-from-scratch-introduction/" rel="nofollow noreferrer">https://www.ashsmith.io/magento2/module-from-scratch-introduction/</a> and this example <a href="https://github.com/ashsmith/magento2-blog-module-tutorial" rel="nofollow noreferrer">https://github.com/ashsmith/magento2-blog-module-tutorial</a> in order to do it.</p>
  <p>Now, I have on page with list of FAQ, but each FAQ is belongs to FAQ Category (Not the Catalog Category).
  So there is two custom modules here (FAQ Category and FAQ Question).
  The FAQ Category only have Title field.
  The FAQ Question have Title field, Answer (text editor) field, and FAQ Question dropdown (select box with list of all availble FAQ categories)</p>
  <p>I don't know how to achive this.</p>
  <p>What is the right way to do it? Especially the admin part.</p>
