Risks



Interoperability and Compatibility



Gecko: No signal (https://github.com/mozilla/standards-positions/issues/631) Pending

WebKit: No signal

Web developers: Positive

Other signals:

WebView application risks

Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?



Goals for experimentation

Test out the current design of the "focugroup" attribute and get feedback from developers to eventually guide spec developement. We are working with the Microsoft FAST team (https://github.com/microsoft/fast) and we expect feedback from them and welcome feedback from the entire web community.



Reason this experiment is being extended



Ongoing technical constraints



Debuggability

Dev tools error logging is supported for various invalid combinations of focusgroup values in HTML.



Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?

Yes

Supported on all platforms but requires a keyboard with directional arrows.



Is this feature fully tested by web-platform-tests?

Yes

Flag name

--enable-blink-features=Focusgroup

Requires code in //chrome?

False
