Joombah is an excellent component for joomla 1.5 and 1.6.
I wanted to be able to add HTML and CSS Tags to my tooltips to format the tooltips as I wanted.
All you have to do is:
1. Open /administrator/components/com_jbjobs/controllers/jbjobs.php
$parent = ($post['type'] == 'group')? 0 : $post['parent'];
3. Add this below the above line:
$post['tips'] = JRequest::getVar('tips', '', 'post', 'string', JREQUEST_ALLOWRAW);
Thanks to the advice from Joombah
