I need help. I've got this code snippet: https://codesandbox.io/s/modern-fog-495lq?file=/src/App.js - there is a problem with expansion of my two tree items. I need to have state of my expansion tree (Child) in Parent Component, but now all of my tree items are expanded/not expanded concurentlly because of the state in Parent Component. Is there any solution to solve this problem? To have expand only one tree when it's clicked on? Thank you for your help.
