Downshift Hooks
Every React hook offers custom logic to build the kind of dropdown you need. If you need to build a combobox then use useCombobox.
However, if you don't need to type a search query and just have a dropdown that is actioned by a button (a select, basically), then use useSelect.
If you need to add multiple selection for any of them and have the selected items act as a Tag List next to the select or combobox, then useMultipleSelection is the right tool for that.
