Often is the case that we must create custom filter panels in text areas - but why stop there?
Make your application stand out. Group similar filters together into an accordion, and then theme it to suit the look and feel of your page or dashboard.
This also includes code to enable multiple headers to be expanded at the same time.
Wiki Articles have no real 'where', just create the wiki page. If you mark the Product Group on it as TIBCO Spotfire, It will appear in the wiki list under the Spotfire product landing page.
Its better as a wiki but it will suffice here too.
Thank you Janine for this information. Can you please move this to wiki instead?
