Form widget group submit

[BJ Freeman <bj...@free-man.net>]

Like to see a check box select of rows that a submit button can act on.
there would be, in the header section, a group check box that when check 
would check all and uncheck would remove all  of the row check boxes.

so if the submit button was to delete  then those rows that are checked 
would be deleted.
  The would require passing a list of ID's or Map to the delete service.

any thoughts.
