<p>By default, the <code>select</code> element does not submit its form when the Enter key is pressed. I am looking for an alternative method—excluding JavaScript—to trigger form submission while the dropdown is active. Even if a workaround only works in quirks mode, it would still be beneficial. How can one achieve this behavior using different techniques or browser-specific settings?</p>
nah, its not really possible without js. u can try quirks mode hacks but its messy and unreliable. html doesn´t have a native way to submit forms with enter when a dropdown is focused so there’s no real workaround.
While native HTML offers no reliable mechanism for using the Enter key to submit a form when a dropdown has focus, an alternative approach is to consider browser-specific settings or legacy mode behavior. In personal testing, certain browsers in quirks mode displayed unexpected form submission behaviors, but this method proved inconsistent and heavily reliant on non-standard implementations. A comprehensive solution without JavaScript remains difficult to achieve. Evaluating these approaches under different conditions suggests that reliance on JavaScript might be a more stable option in practice.
