The following should help you get going. Based on your info and missing full HTML code, i just put basic selectors.

 $(document).ready(function() { var i = 0; $('select').change(function() { i++; $('table tr:last').after('<tr id="row' + i + '"><td><input type="text" name="name[]" placeholder="Enter your Name" class="form-control name_list" /></td> <td><button type="button" name="remove" id="' + i + '" class="btn btn-danger btn_remove">X</button></td></tr>'); }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <table> <tr> <td> <label for="Category">Category</label> <select class="form-control" name="product-categorie[]"> <option>Select Product Category</option> <option value="1">Some Name 1</option> <option value="2">Some Name 2</option> </select> </td> </tr> </table>
