Collection broken again!

Now swear I will!
Again broke the collection?
All that is in row should be col-classes
You need use 3 classes - label, widget and remove btn 
or add row to widget

div "formGroup"
   div label col-3
   div widget col-3
   div del col-3

(i do this)

or

div "formGroup"
   div label col-3
   row
      div widget col-9
      div del col-3

or if in new line

div "formGroup"
   row
      div label col-3
      div widget col-9
   row
      div del col-12
