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? No.



Goals for experimentation

Test out the current design of the "focugroup" attribute and get feedback from developers to eventually guide spec development. We are working with UX teams at Microsoft that plan on building on top of this feature and we expect feedback from them and welcome feedback from the entire web community.



Ongoing technical constraints

None.

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)?

No. It requires a keyboard with directional arrows, so it won't work on mobile/touch devices deprived of such keys.

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

Yes (well, 2 out 3 of my CLs converting blink unit tests into web platform tests have been approved to merge and will soon. The third one will follow this week as well) 

Flag name

--enable-blink-features=Focusgroup

Requires code in //chrome?

False

Tracking bug

https://bugs.chromium.org/p/chromium/issues/detail?id=1286127

Estimated milestones

Seems worthwhile to start a TAG review for this.

You don't often get email from yoav...@chromium.org. Learn why this is important

Just curious -- will this work on Android if I plug in a keyboard into
my phone/tablet? (I.e. is this blocked by an #ifdef, or just an effect
of not normally getting keyboard events)

No #ifdef, just physical limitations. You are free to try it out today if you want!
