dropAlign

How to align the drop with respect to the button.

To prevent creating a new object on each render, the align property should be persistent, either as a static constant outside of the render function or memo-ized using hooks.

React/DOM Properties

At its core, the DropButton component is a regular <button> element. Thus, both DOM and React properties, methods, and events are accessible. To read up on all of the possible DOM attributes and types available for button elements, check out this MDN Web Documents page. To learn more about DOM events and methods, you can read more on the MDN Web Events documentation page.

Also, feel free to read about the types of React events available, or see how DOM attributes change in React. Working in tandem with Styled Components, you also have access to the as property.
