 Hello Everyone..

I am new to Jasper server and learning how to create reports using Ireport and deploying it on Jasperserver.I want to use the option of expanding :

                                       for eg:-       + Countries

On clicking + sign It should expand and show further details as in this case will be list of countries.

 

Please help me to learn Jasperreports better.

Regards,

Mandeep
