Select Props

children: PropTypes.node.isRequired (Accepts 2 children)

The first child is used as the trigger and the second child is used as the options that will be displayed upon clicking the trigger.

multiple: PropTypes.bool

When true this allows multiple options to be selected.

disabled: PropTypes.bool

Puts the select menu in a disabled state.

autoWidth: PropTypes.bool

Determines if the options should be the same width as the trigger.

onChange: PropTypes.func

Callback when an option has been selected. Passes back the value that was selected.

React ARIA Components

Trigger, OptionList, and Option are exported directly from React ARIA
