Bootstrap Accordion with PHP script not working properly - php

Question

I have written a php script which uses Bootstrap Accordion.
My Problem is as follows:-
Data is displayed correctly in the accordion for all records but when i click on respective accordion..none of them pop-open n close except the accordion of the very first record displayed i.e only the first accordion is working perfectly fine but for rest of the records, accordion displays correct data but does not pop-open n close at all.
Please help if anyone can
Here is the code which i have written
<div class="row">
<?php while ($row = mysql_fetch_assoc($sql_result)) { ?>
