Hi Srinivas,
I do it like this. But I'm just doing these things for fun, therefore the
code is maybe not the best.

Hi,
How to use jig for multiple entities.
Suppose if i want to move more than one entity and want to move those
entities visually while mouse move, how to use jig without creating entities
as a block?
Thanks in advance.
Regards,
Srinivas.
