  My tree of subjects has two primary subjects, which have “N” sub- subjects. Many subjects are repeated, but they have different primary  subjects, at the time of recording a subjects, i need to record in addition, to as primary subjects belongs (to distinguish from where it comes),therefore, i need to know as it is the primary root (in JavaScript), when they select some subject (As it shows the sample), Is possible to know this data?, thanks
