THE GOLDEN RULE OF CUSTOMIZABLE SELECT

Summary from the TLDR newsletter

Customizable select, a new feature coming to Safari 27, allows developers to fully control the appearance of 'select' elements without the need for JavaScript libraries or endless 'div' elements. Ensuring this built-in control works well for everyone requires making sure developers always provide text content or accessible text attributes in their 'option' elements. This provides a better UX, better accessibility, and better progressive enhancement.
