Fully Stylable Custom Dropdown

This snippet recreates the visual effect of a fully-themed dropdown, including options and checkmarks, as demonstrated in the video's '2025' segment. While the video highlights future native CSS styling with `appearance: base-select`, this demo achieves the desired look and feel using custom HTML, CSS, and JavaScript due to current browser limitations.
