Default expanded keys

If you want to expand some items by default, you can set the defaultExpandedKeys property to an array of keys.

Disabled keys

If you want to disable some items, you can set the disabledKeys property to an array of keys.

Start content

If you want to display some content before the accordion items, you can set the startContent property.

Custom Indicator

Accordion items have a property called indicator. You can use it to customize the open/close indicator.

The indicator can be also a function, which receives the isOpen, isDisabled and the default indicator as parameters.

Custom Motion
