Bug ID: 25473
Summary: [Custom]: Add support for focus navigation similar to
input type=date
Product: WebAppsWG
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: Component Model

See the following example (in Chrome):

Imagine if <input type="date"> element was implemented as a custom element. The
author would need to create the custom focus behavior this element has.
Special behavior occurs when focus enters and leaves the element. When focus
enters the element in the forward navigation direction, the element needs to
focus the month field. When the focus enters the element in the backward
direction, the element needs to focus the year field. When the focus leaves the
month field in the backwards direction, the element needs to shift focus from
itself to the previous element in the focus flow. When the focus leaves the
year field in the forward direction, the element can simply let the focus
naturally flow to the next element.
Here's a strawman for one way this could work:
- add willFocusCallback and willBlurCallback custom element callbacks and
provide the focus navigation direction and currently focused element as
arguments.
- add a way to tell the platform to focus the 'next' or 'previous' element in
the focus flow.
