updation:

whenever i create a child to ranikannur gives me 3 children with same name in each root ranikannur,in my database there is only one child is parented by ranikannur but treelist shows it as 3 children in each parent node,the children count 3 is getting from the total ranikannurparent nodes(here tree has 3 ranikannur parent nodes) i guess.how is this getting the 3 children?
