input.blur()Removes cursor focus from the input.
input.focus()Moves cursor focus to the input.
input.valueA getter/setter for the input value. If attempting to set a non-string value it will be stringified.
listBox.collapse()Collapses the listbox if currently expanded.
listBox.expand()Expands the listbox if currently collapsed.
listBox.activeOptionA getter for the currently active option.
listBox.isExpandedA getter for the current listbox state. Returns a suggested option or null.
select()Triggers the select function to add or remove the currently highlighted option.
It is possible to customize the appearance of the component using CSS, the included styles found in /example/styles.css are only an example. Custom class names can be provided to the component via the classNames prop.
