	Prompt:
	We have defined a basic dropdown via the Dropdown and DropdownItem components below, with example usage
	in the ExampleNav component. The Dropdown and DropdownItem components have some problems, and also
	have room for improvements (doesn't everything?) A couple items TODO here (make sure to explain with comments!)

	0. How are you today? 😊
	1. Please fix any obvious issues you see with the dropdown.
	2. Please then make improvements to the dropdown and make it a bit more React-y. Assume this was cobbled
	together or brought in hastily from StackOverflow.
