I need some help with React. As far as I know, it should be working just fine. But, it is not working. What I am trying to do is :
I have a list of todo.
You can add new todo and you can also expand the todo section.
When you expand the todo section, it will open up full screen.
The problem is, newly added todos are not showing up when you expand the todo. Why is that? I am basically using the same component. Why is it that the newly added todos dissapeared when todo section is expanded? And vice-versa, when you expand, add new todo and close the modal, newly added todos are not showing up. How can I make new todo persists regardless of the todo section is expanded or not.
Please, take a look at the small demo app I built.
