xBrowser How to display customers/city a kind of treeview

Finally I would consider this kind of requirements as issues where we need to find optimal solutions case by case. If it is small regular look up table, we better keep it in array than to keep reading everytime all the way from the server. For large tables this kind of display may not be necessary. In any case we should implement the best solution in each case than trying to find a common solution.
