Kindly may i know when a tree gets expanded in zope does it rebuild from root (starting position) or it gets rebuild from the place it gets expanded.

Usually, the hierarchy is simply there, the tree tag just displays part of it. The table representing the tree is regenerated for each request from scratch. Thus, the "branches" method (or "branches_expr") is recalled for all visible tree nodes and not only for the expanded node. Dieter
