Using multiple MaterialUI components in a JavaScript page with React can pose challenges

Incorporating multiple MaterialUI Cards in my project, I encountered an issue where all the cards would expand or the select values would change simultaneously. Despite using unique key values and mapped components with distinct keys, the problem persisted.

As a newcomer to React and MUI, it seems to be related to an id issue. Should I pass key values to the onChange methods of each component to ensure that only the relevant card expands or select value changes? How can this be achieved?

Since you are utilizing one boolean for all three cards, consider using ids or names to specify the card you want:

const handleToggleClick = (panel, isToggled) => () => {
  // close panel if it's already open, otherwise open it
  setToggled(isToggled ? false : panel);
};

<ToggleMore
  toggle={toggled === recipe.name}
  onClick={handleToggleClick(recipe.name, toggled === recipe.name)}
  aria-toggled={toggled === recipe.name}
  aria-label="display more"
>

Also, here's your collapse component:

<Collapse
  in={toggled === recipe.name}
  timeout="auto"
  unmountOnExit
>

To keep things DRY, you can declare a variable at the start of the map:

const isToggled = toggled === recipe.name
