title: Bootstrap Dual Listbox send
body: <p>I'm using Bootstrap Dual Listbox to select multiple data and to show the user how many persons will be in a oficial list and who won't.
  You can see an example on this page: <a href="http://www.virtuosoft.eu/code/bootstrap-duallistbox/" rel="nofollow noreferrer">http://www.virtuosoft.eu/code/bootstrap-duallistbox/</a></p>
  
  <p>The point is that, even though it works, I would like to know How do I know which box has the selected items and send them through POST using PHP, because the only "select" tag that you can see in HTML is the only one with all the options that you want to select, and when you are moving the data side to side it creates to containers dynamically call box1 and box2.</p>
  
  <p>The code it is almost the same of this link, 'cause I couldn't write down the code here,don't know why it didn't display all the code (new one): <a href="https://stackoverflow.com/questions/31859295/bootstrap-dual-listbox-how-to-limit-selected-option">Bootstrap Dual Listbox : How to Limit Selected Option</a>, but is not the question that I was looking for.</p>
  
  <p>Hope you understand my point!! </p>
  
  <p>Thank you very much!</p>
