title: Dynamically create and repeat the set of fields
body: <p>I have a PHP form which shows one 'User details' block by default. 'User details' section has  first name, last name and address etc.  I have a requirement to repeat the same block after  clicking on the button so the user can enter 'n' number of users into on the form. Also I need to save all the information in MySQL database. What is the best way to achieve this? Please let me know. I appreciate any help.</p>
  
  <p>Thank you.</p>
