@spark-ui/dropdown/dist/types.d.ts

Displays a list of options for the user to pick from—triggered by a button. Differs from Select in that it offers multiple select and its list is not native.

import { UseMultipleSelectionReturnValue, type UseSelectReturnValue } from 'downshift';
export interface DropdownItem {
    disabled: boolean;
    value: string;
    text: string;
}
export type ItemsMap = Map<string, DropdownItem>;
export type DownshiftState = UseSelectReturnValue<DropdownItem> & UseMultipleSelectionReturnValue<DropdownItem>;
