I friends,

I have a problem. I have a DataSet with 3 tables.

1 Table is the parent, and the other two are the children.

I have a group with the father, I would like to have 2 groups

in the same level. How can I do it?

For example: I have, cars( parent), name of wheels(first sons) and name of the brakes(second sons).
If i want to list the name of the cars,
and then the name of wheels of each car, and in the same level, the name of the brakes.


I mean:


ford
  firestone
  michelin
  brake1
  brake2
ferrari
  firestone
  michelin
  brake1
  brake2
  ....

Thank u
