View Full Version : Collapsible table sorting problem

Hello all,

I have a very simple html table with collapsible rows and sorting capabilities. The collapsible row is hidden with css rule (display:none). When one clicks in the left of the expandable row, the hidden row is made visible with css. The problem is when i sort the rows, the hidden rows get sorted as well which i don't want and want to be moved (while sorting) relative to their parent rows. The following is my complete html code with javascript. Just copy the entire code to new html file and see the problem yourselves. Any suggestions/help would be greatly appreciated.



<html>
<head>
<title>Expandible row test in firefox</title>
<STYLE type="text/css">
.collapsed
{
DISPLAY: none;
}
</STYLE>

<script language="javascript" type="text/javascript">

Thank you so much for the code. I would appreciate if you could change the existing sorting algorithm (that i am using) to make it work. Hope to hear you.

Sincerely,
