Accordion: How to specify expanded items with Item component

created 2 days ago

Hi,

We use the Accordion component in our React app with the Item component to define the list of accordion items. We could like to use the component in controlled mode for the expanded items and use multiple={true} so let the user expand multiple items. How can we do this?

  • selectedIndex only accepts a single value, so it doesn't work for multiple expanded items
  • selectedItems expects a list of item objects (I guess?), which we don't have when we use the Item component
  • selectedItemKeys expects a list of keys, but how can we define item key when we use the Item component?

Regards,
Sandro

Hello,

You can set Accordion|keyExpr to title in this case because each Item allows you to define this field. Then, you can define the selectedItemKeys property to display required items in the expanded state.
If you need to allow users to collapse these items, you can handle onSelectionChanged to change the selectedItemKeys property. Please refer to the following example as a starting point: CodeSandBox
Alternatively, you can define defaultSelectedItemKeys if you don't need to track the current selection state.

Let me know if this solution helps.
