The following worked for me:
1. Upload the sort table javascript file named "sorttable.js" from here
www.kryogenix.org/code/browser/sorttable/ (I put it in /templates/rt_audacity/custom/sorttable.js)
2. Install the "Add Custom Javascript" plugin to load the table sort javascript in the Head section from here
joomla.impression-estudio.gr/en/joomla-e...dd-custom-javascript
3. Enter the location of your table sort javascript in the plugin's parameter & Enable the plugin
4. Add <table class="sortable"> html in the RSJoomla Submission module in the "Module Layout" text box as instructed by
www.kryogenix.org/code/browser/sorttable/ Example below
<table class="sortable">
<thead>
<tr><th>Person</th><th>Monthly pay</th></tr>
</thead>
<tbody>
<tr><td>Jan Molby</td><td>£12,000</td></tr>
<tr><td>Steve Nicol</td><td>£8,500</td></tr>
<tr><td>Steve McMahon</td><td>£9,200</td></tr>
<tr><td>John Barnes</td><td>£15,300</td></tr>
</tbody>
<tfoot>
<tr><td>TOTAL</td><td>£45,000</td></tr>
</tfoot>
</table>
The Add Custom Javascript plugin will ensure your sort table script will not be overwritten by future template or Joomla upgrades.
I hope this is helpful to anyone wanting to add a sort feature to all the columns in a form submissions module.
It would be great if this feature could be included in a future release of the RSForm Pro! List Submissions Module !!!
It is a great feature for the submissions module & one that will help RSJoomla Form Pro stand out from the other form builder extensions.
