title: How to enable an item selection from selectbox in CKEditior4
body: <p>I'm using CKEditor4 to prepare document templates. And then these templates are used to create documents, but also with CKEditor. So, I want to use in the template select items such as enum values, which value I can select later, in a document.</p>
  
  <p>But editor doesn't allow me to select any value from form element. 
  Is there any way to make this item active? </p>
  
  <p>Or, maybe, there is any plugin, which provides same features?</p>
