I have an application where I need to select an item in a three-level list. That is, one column is the top level and others are formed relative to it. But if you select the lower level, then the upper ones should automatically become relative to the lower level. Initial value does not work well, for example, when I already select something in this column, then when I select something in lower level, nothing happens there. Is it possible to solve this problem somehow?
