Chrome 135 introduces support for the Customizable Select Element standard, paving the way for developers to customize options within the tag. This allows for complex modifications such as adding images to options or setting different background colors for each option.
Previously, modifying the tag display required JavaScript. With this update, it can now be achieved solely using HTML and CSS, with the added benefit of being able to predict the display outcome if accessed on browsers that do not support the new standard.
To begin using this feature, one must declare appearance: base-select to prompt the browser to change its rendering mode. Failure to do so on unsupported browsers will result in the options not being read and displayed like a regular form.
While Chrome is the first to support this standard, Google acknowledges the collaborative effort of other manufacturers in defining the standard, hinting at possible future additions to make form customization even more intricate.
TLDR: Chrome 135 introduces support for Customizable Select Element, allowing developers to customize tag options without relying on JavaScript, using HTML and CSS instead. Collaboration with other manufacturers indicates future enhancements for form customization.
