SelectMultiple is a dropdown component that enables the user to quickly scan the list of options and choose more than one of the options.
The SelectMultiple component is typically used as a form element but can also be leveraged for user experiences that include searching or narrowing down data. It contains an optional search field. When within a form, the SelectMultiple will support labels, error and disabled states.
When to use
When multiple selections can be made in a list that contains 5 or more items.
When not to use
- For lists that offer less than 5 options, consider using a CheckBoxGroup instead.
- When only a single selection is permitted, use the Select component instead.

- Ordering of lists - chronological/recency
- Search: Consider including a search if your list is 10 items or longer to make it easier to browse options.
