How to achieve Expand and Collapse on Row/Record/Group Level in Jasper Report?

[abidi]

I am using a Jasper Server Community Edition. I wanted to know if I can achieve expand and collapse (hide and show) on group level in jasper reports. What components I will use to achieve this? On the same report the report will display the records as a tree with + or – for a group and user can expand the group and drill down further to view the records etc. Do let me know if it is not part of Jasper Server Community Edition.

Thanks,

I use commercial version (Jaspersoft studio 6.3.0) and it doesn't have this feature when preview. 

When export to excel, you can follow the link below to acheve this feature.
