Can anyone give me an idea how I can use tabSheet where the contents of the fieldgroup will be manipulated in few tabs?
You can create multuple FieldGroup instances with different set of fields and the same datasource on TabSheet tabs. Just add new FieldGroup to TabSheet tab, set datasource and add fields for this FieldGroup.
Thanks. I want to move the fields that is created by the tool automatically inside the FieldGroup to the new FieldGroups I will create, is there any way to do that?
There is no automatic way, but you can do it manually from Studio or using your IDE by editing XML of the screen.
