Accessibility

Screen Readers

Picker supports navigation using a screen reader by implementing the slider role on each Picker Column. The following gestures can be used to navigate the Picker.

Gesture	Function
Swipe Left	Move focus to the previous Picker Column.
Swipe Right	Move focus to the next Picker Column.
Swipe Up	Select the next option in the Picker Column.
Swipe Down	Select the previous option in the Picker Column.
Double Tap and Slide Up/Down	Adjust the selected option in the Picker Column. Can be used as an alternative to swiping up and down.

注意

The Swipe Up and Swipe Down gestures rely on the correct key events being synthesized as noted on the slider documentation. Chromium-based browsers do not synthesize keyboard events correctly, but the "Double Tap and Slide Up/Down" gesture can be used as an alternative until this has been implemented in Chromium-based browsers.

Keyboard Navigation

Each Picker Column can be navigated using the keyboard when focused.

Key	Function
ArrowUp	Scroll to the previous option.
ArrowDown	Scroll to the next option.
PageUp	Scroll up by more than one option.
PageDown	Scroll down by more than one option.
Home	Scroll to the first option.
End	Scroll to the last option.
