title: Add new fields to create_account.jsp without custom fields functionality in Liferay
body: <p>I want to add 15 new fields to my user account creation page in Liferay. How it is possible other than custom fields, expando tables? Because I know how to use custom fields. I have more fields so it will be difficult to manage. Through hook I want to add more fields to account creation page.</p>
  
  <ul>
  <li><p>Fields are related to user.</p></li>
  <li><p>Create one selectbox that will have list of organizations available in my application.</p></li>
  <li><p>Create one selectbox that will have list of roles available in my application.</p></li>
  <li><p>onclicking of save button that should redirect to 3rd party payment gateway. Once paid amount it will create account for that user.</p></li>
  <li><p>After paid amount all the above fields need to add under extra table with related columns and maps to the <code>user_ table</code> with <code>userId</code> as a primary key.
  assign that organization to the user which is selected above and similar for role also.</p></li>
  </ul>
  
  <p>I am using Liferay 6.2. Please let me know if any one have any ideas!</p>
