Ok, so heres my question. I have a select dropdown that is populated from my table, category_names. I am getting the id and the name and using the id as the value. And the name as the select name.

Code:
<?php
      include("./config.php");
      $query="SELECT id,name FROM category_names";
      $result = mysql_query ($query);
      echo "<strong>Pick as many that fit your business</strong><br/><br/>";
      echo"<div style='overflow:auto;height:300px;width:100%'><select>";
      // while loop
      while($nt=mysql_fetch_array($result)){//Array or records stored in $nt


      echo "<option value=NAME=$nt[id]>$nt[name]</option><br/>

";

      }?>
Ok so that populates my select. But now I want to hit a little "ADD" hyperlink at the bottom and another identical select dropdown to appear underneath that is also populated from my database. And each select needs to add to a different row in table. How do I achieve this?
