Optionally utilize customDisplay on the Dropdown.Trigger subcomponent to customize its content after an option is selected. Pass in any combination of kits to create a custom display. When a user clicks on an option, the kits passed into customDisplay will display as the selected option.

The placeholder prop can also be used to customize the placeholder text for the default Dropdown.Trigger.

The onSelect prop returns the selected option as an object to be utilized by the dev. In this example we are using the onSelect to set a state with the selected option and using it to customize the customDisplay.
