title: Dynamically add fields based on select list apex 4.2
body: <p>I'm developing in apex 4.2 and currently I'm having some issues with my form.
  I want to (dynamically) add textfields/regions based on the number that is selected in a selectlist.</p>
  
  <p>So when  I select 6, i want to see 6 regions with the same kind of textfields in it. 
  Now i've made 6 regions myself and I have added some show/hide dynamic actions on it, but isn't there some kind of way to do this without having to manually add regions ? </p>
